blk-mq-debugfs: Add decode for BLK_MQ_F_TAG_HCTX_SHARED

[ Upstream commit 02f938e9fed1681791605ca8b96c2d9da9355f6a ]

Showing the hctx flags for when BLK_MQ_F_TAG_HCTX_SHARED is set gives
something like:

root@debian:/home/john# more /sys/kernel/debug/block/sda/hctx0/flags
alloc_policy=FIFO SHOULD_MERGE|TAG_QUEUE_SHARED|3

Add the decoding for that flag.
