Commit f1e155bbf863a removed a bunch of stuff that really don't make sense
outside the linux kernel. An exception though is logging functions: it is
convenient to be able to grep error messages in the code. For this to work,
error strings mustn't be broken down on multiple lines, and therefore are
likely to overcome the 90 characters limit, and make checkpatch unhappy.
This patch reverts the change for logging functions and adapts it to QEMU.
