[S390] cio: Restart path verification after unsolicited interrupt.
If we try to start path verification when an unsolicited interrupt
is already pending, stctl shows status pending and we delay path
verification again. We need to check for the doverify bit when the
unsolicited interrupt comes in and then do path verification.
