Tony Battersby 53661ded24 scsi: qla2xxx: Disable ATIO interrupt coalesce for quad port ISP27XX
This partially reverts commit d2b292c3f6 ("scsi: qla2xxx: Enable ATIO
interrupt handshake for ISP27XX")

For some workloads where the host sends a batch of commands and then
pauses, ATIO interrupt coalesce can cause some incoming ATIO entries to be
ignored for extended periods of time, resulting in slow performance,
timeouts, and aborted commands.

Disable interrupt coalesce and re-enable the dedicated ATIO MSI-X
interrupt.
