refresh_limits is not doing anything for block devices, and is retrieving
the maximum number of s/g list entries incorrectly for character devices.
Patches 2-3 fix these problems, while patch 1 is a small improvement to
avoid making the BlockLimits unnecessarily restrictive when SG_IO is not
in use.

Paolo Bonzini (3):
scsi-generic: pass max_segments via max_iov field in BlockLimits
file-posix: try BLKSECTGET on block devices too, do not round to power
of 2
file-posix: fix max_iov for /dev/sg devices
