Under heavy load the target stops responding, the drivers aborts
timeout and we start recovery by logging out of the target, but
the target is never logged into again.

In a point-to-point scenario, there were battling PLOGI's. When we
received a PLOGI request after having sent one, the driver cancels
the processing of the original plogi. However, the completion path
of the remaining plogi was coded to skip the reg_rpi that should
be happening on the 2nd plogi.

Correct by adding a simple pt2pt check such that the 2nd plogi isn't
skipped and the reg_login occurs.
