The "ibmvscsi: treat busy and error conditions separately" patch
submitted by Dave Boutcher back in June incorrectly reenables the CRQ.
The broken logic causes the adapter to get disabled if the CRQ
connection happens to close temporarily. This patch "fixes that
obviously wrong logic check" (Dave's words).

- Drop queue-depths across all luns for a given fcport
during TASK_SET_FULL statuses.
- Ramp-up I/Os after throttling.
- Consolidate completion-status handling of CS_QUEUE_FULL with
CS_COMPLETE as ISP24xx firmware no longer reports
CS_QUEUE_FULL.

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state. This issue can result in a hung PCIe
link. Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.
In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully. In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.

Thanks to James Smart for the inspiration.
Stall error handler if attempting recovery while an rport is blocked.
This avoids device offline scenarios due to errors in the error handler.
Also verify that VirtDevice is available before issuing scsi command.
VirtDevice is removed when fc transport removes a target.
See James Smart's patch of 08/17/2006 for greater detail.

were updated, causing the obvious linker error. Remove caller,
because the check (like the one removed) isn't used.
