Revert "brd: remove discard support"

This reverts commit f09a06a193d942a12c1a33c153388b3962222006.

To support ramdisk flush, discard is required. So, revert the commit.
Note: struct queue_limit::discard_zeroes_data flag setting is
removed and queue_flag_set_unlocked() is replaced
blk_queue_flag_set().
