scsi: ufs: core: Do not exit ufshcd_err_handler() unless operational or dead

Browse source

Callers of ufshcd_err_handler() expect it to return in an operational
state. However, the code does not check the state before exiting.

Add a check for the state and perform retries until either success or the
maximum number of retries is reached.
