block: use BDRV_O_NOCACHE instead of s->aligned_buf in raw-posix.c
Rather than check for a non-NULL aligned_buf to determine if raw_aio_submit needs to check for alignment, check for the presence of BDRV_O_NOCACHE in the bs->open_flags. Signed-off-by: Jeff Cody <jcody@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
