Zheng QixingandGreg Kroah-Hartman 549cbbd14b block: fix resource leak in blk_register_queue() error path ...

[ Upstream commit 40f2eb9b53 ]

When registering a queue fails after blk_mq_sysfs_register() is
successful but the function later encounters an error, we need
to clean up the blk_mq_sysfs resources.

Add the missing blk_mq_sysfs_unregister() call in the error path
to properly clean up these resources and prevent a memory leak.

Fixes: 320ae51fee ("blk-mq: new multi-queue block IO queueing mechanism")
