scsi: ufs: Suppress false positive unhandled interrupt messages

From ufshcd_transfer_req_compl():

    Resetting interrupt aggregation counters first and reading the
    DOOR_BELL afterward allows us to handle all the completed requests.  In
    order to prevent other interrupts starvation the DB is read once after
    reset. The down side of this solution is the possibility of false
    interrupt if device completes another request after resetting
    aggregation and before reading the DB.

Prevent that ufshcd_intr() reports a false positive "Unhandled interrupt"
message if the above scenario is triggered.
