iscsi: fix assertion in is_sector_request_lun_aligned
Commit
94d047a added an assertion the the request alignment check.
This introduced 2 issues:
a) A off-by-one error since a request of BDRV_REQUEST_MAX_SECTORS
is actually allowed.
b) The bdrv_get_block_status call in the read path to check the allocation
status requests up to INT_MAX sectors which triggers the assertion.
