block: adjust blkdev_issue_discard for swap
Two mods to blkdev_issue_discard(), thinking ahead to its use on swap:
1. Add gfp_mask argument, so swap allocation can use it where GFP_KERNEL
might deadlock but GFP_NOIO is safe.
2. Enlarge nr_sects argument from unsigned to sector_t: unsigned long is
enough to cover a whole swap area, but sector_t suits any partition.
Change sb_issue_discard()'s nr_blocks to sector_t too; but no need seen
for a gfp_mask there, just pass GFP_KERNEL down to blkdev_issue_discard().
