[PATCH 3/7] blk-mq: remove wake_batch recalculation for reserved tags

[Kemeng Shi <shikemeng@huaweicloud.com>]

Commit 180dccb0dba4f ("blk-mq: fix tag_get wait task can't be
awakened") added wake_batch recalculation when user number of shared
tags changes to avoid hung as user number increases, then hctx_max_depth
limit for a single user decreases and may trigger hung if wake_batch >
hctx_max_depth is met.
Commit 285008501c65a ("blk-mq: always allow reserved allocation in
hctx_may_queue") removed hctx_max_depth limit to alloc reserved
tags, so hctx_max_depth limit for reserved tags is not exisiting anymore
so we can remove recalculation for reserved tags.

Fixes: 285008501c65 ("blk-mq: always allow reserved allocation in hctx_may_queue")
