Yaniv Gardi 53c12d0ef6 scsi: ufs: fix error recovery after the hibern8 exit failure
Hibern8 exit can be called from 3 different contexts:
    - ufshcd_hibern8_exit_work
    - ufshcd_ungate_work
    - runtime/system resume

If hibern8 exit fails for some reason then we try to bring the link to
active state by link startup but this recovery mechanism results into
deadlock or errors from first 2 context listed above. This change fixes
the recovery by adding proper error handling mechanism.
