Add isp_fc_runstate function- this function's purpose is to, in stages, 

and depending on role, make sure link is up, scan the fabric (if we're
connected to a fabric), scan the local loop (if appropriate), merge
the results into the local port database then, check once again
to make sure we have f/w at FW_READY state and the the loopstate
is LOOP_READY.

* the fabric (if we're on a fabric), and that we've synchronized this

*
* We repeatedly check for firmware state and loop state after each
* action because things may have changed while we were doing this.
* Any failure or change of state causes us to return a nonzero value.

* We honor HBA roles in that if we're not in Initiator mode, we don't

* if ever).

* We assume we enter here with any locks held.
