[SCSI] qla2xxx: Properly acknowledge IDC notification messages.
To ensure smooth operations amongst the FCoE and NIC side
components of the ISP81xx chip, the FCoE driver (qla2xxx) must
ensure the 10gb NIC driver (qlge) does not timeout waiting for
IDC (Inter-Driver Communication) acknowledgments. The
acknowledgment requirements are trivial -- a simple mirroring of
incoming mailbox registers during the AEN to a process-context
capable mailbox command.
