scsi: ufs: Fix livelock of ufshcd_clear_ua_wluns()

When gate_work/ungate_work experience an error during hibern8_enter or exit
we can livelock:

 ufshcd_err_handler()
   ufshcd_scsi_block_requests()
   ufshcd_reset_and_restore()
     ufshcd_clear_ua_wluns() -> stuck
   ufshcd_scsi_unblock_requests()

In order to avoid this, ufshcd_clear_ua_wluns() can be called per recovery
flows such as suspend/resume, link_recovery, and error_handler.
