Fix for discovery failure in PT2PT when FLOGI's ELS ACC response gets aborted

Change login state machine to:

- Reject incoming FLOGIs if we have one pending

Currently, the driver plays off the fact that older sli4 adapters have a
different rpi access pattern that allowed for the rpi reference to be
released earlier in the teardown sequence, allowing the driver to recycle
the rpi value sooner. Newer sli4 adapters have a different access pattern that
requires us to wait for a later mailbox completion. This changes the put
call location on the newer sli4 adapters.

Symptoms of the error are "0110 ELS" and the "0372 iotag" errors.

resumes transmit operations after a link bounce. Without it, targets
that tried to suspend exchanges after a link bounce (such as tape devices
using sequence level error recovery) would never resume io operation,
causing scan failures, and eventually deadlocks if a device removal
request is made.
