block: Revert "block: Fix potential deadlock while freezing queue and acquiring sysfs_lock"
This reverts commit be26ba96421ab0a8fa2055ccf7db7832a13c44d2.
Commit be26ba96421a ("block: Fix potential deadlock while freezing queue and
acquiring sysfs_loc") actually reverts commit 22465bbac53c ("blk-mq: move cpuhp
callback registering out of q->sysfs_lock"), and causes the original resctrl
lockdep warning.
So revert it and we need to fix the issue in another way.
