vfio/ccw: allocate irq info with the right size
When allocating memory for the vfio_irq_info parameter of the
VFIO_DEVICE_GET_IRQ_INFO ioctl, we used the wrong size. Let's
fix it by using the right size.

vfio/ccw: fix initialization of the Object DeviceState pointer in the common
base-device
Commit 7da624e2 ("vfio: Test realized when using VFIOGroup.device_list
iterator") introduced a pointer to the Object DeviceState in the VFIO
common base-device and skipped non-realized devices as we iterate
VFIOGroup.device_list. While it missed to initialize the pointer for
the vfio-ccw case. Let's fix it.

s390/cpumodel: remove KSS from the default model of z14
The SIE_KSS feature will allow a guest to use KSS for a nested guest.
To create a nested guest the SIE_F2 facility is still necessary.
Since SIE_F2 is not part of the default model it does not make
a lot of sense to provide the SIE_KSS feature in the default model.
Let's also create a dependency check.

target/s390x: improve baselining if certain base features are missing
There are certain features that we put into base models, but that are
not relevant for the actual search. The most famous example are
MSA subfunctions that might be disabled on certain real hardware out
there.
While the kvm host model detection will usually detect the correct model
on such machines (as it will in the common case not pass features to check
for into s390_find_cpu_def()), baselining will fall back to a quite old
model just because some MSA subfunctions are missing.
Let's improve that by ignoring lack of these features while performing
the search for a base model.

s390x/css: fix ilen in IO instruction handlers
When initiating a program check interruption by calling program_interrupt
the instruction length (ilen) of the current instruction is supplied as
the third parameter.
On s390x all the IO instructions are of instruction format S and their
ilen is 4. The calls to program_interrupt (introduced by commits
7b18aad543 ("s390: Add channel I/O instructions.", 2013-01-24) and
61bf0dcb2e ("s390x/ioinst: Add missing alignment checks for IO
instructions", 2013-06-21)) however use ilen == 2.
This is probably due to a confusion between ilen which specifies the
instruction length in bytes and ILC which does the same but in halfwords.
If kvm_enabled() this does not actually matter, because the ilen
parameter of program_interrupt is effectively unused.
Let's provide the correct ilen to program_interrupt.
