[Devel] [PATCH RH7 1/2] ploop: Pass correct argument in kaio_sync_read_many()

[Kirill Tkhai]

AIO argument has to be passed here, while READ_SYNC results
in permanent EINVAL.

The fix has no visible effect, as this function is currently
unused (kaio is not populating holes_bitmap on mount at the moment).
