block: bdrv_aio_* do not return NULL
Initially done with the following semantic patch: @ rule1 @ expression E; statement S; @@ E = ( bdrv_aio_readv | bdrv_aio_writev | bdrv_aio_flush | bdrv_aio_discard | bdrv_aio_ioctl ) (...); ( - if (E == NULL) { ... } | - if (E) { <... S ...> } ) which however missed the occurrence in block/blkverify.c (as it should have done), and left behind some unused variables.
