Revert "scsi: ufs: core: Fix devfreq deadlocks"

This reverts commit b03f7ed9 which is
commit ba810437 upstream.

It breaks the Android kernel ABI and only affects one platform (some
Qualcomm systems.)  If it is needed back, it can be done so in an
ABI-stable way by the platform owners if they so desire.
