Revert "FROMLIST: scsi: ufs: Fix deadlocks between power management and error handler"

Browse Source 
This reverts commit f68d040c31.

Patch "scsi: ufs: core: Reduce the power mode change timeout" caused a
spike in the number of UFS suspend timeouts. Hence revert that change
and also later UFS driver changes.
