scsi: ufs: add wrapper for retrying sending query attribute

Browse source

Sometimes queries from the device might return a failure so it is
recommended to retry sending the query, before giving up.  This change
adds a wrapper to retry sending a query attribute, in cases where we
need to wait longer, before we continue, or before reporting a failure.
