block: fix oops on !disk->queue and sysfs discard alignment display
Eric Dumazet reports: ---- At boot, I have a crash in part_discard_alignment_show+0x1b/0x50 CR2 : 000006ac fault in : mov 0x2c(%rcx),%edx I suspect commit 23ceb5b7719e9276d4 (block: Remove extra discard_alignment from hd_struct) being in fault ---- Not quite known how ->queue can be NULL while the sysfs entry exists, but lets play it safe and check for a NULL queue. The rest of the sysfs show strategies in check.c do not dereference disk->queue. Reported-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
