Since commit c25f53b06e ("raw: Probe
required direct I/O alignment") QEMU has failed to launch if image files
produce I/O errors.
Previously, QEMU would launch successfully and the guest would see the
errors when attempting I/O.
This is a regression and may prevent multipath I/O inside the guest,
where QEMU must launch and let the guest figure out by itself which
disks are online.
Tweak the alignment probing code in raw-posix.c to explicitly look for
EINVAL on Linux instead of bailing. The kernel refuses misaligned
requests with this error code and other error codes can be ignored.
