The LLDD calls this routine to notify the transport that the
roles on a remote port may have changed. The largest effect of this is
if a port now becomes a FCP Target, it must be allocated a
scsi target id. If the port is no longer a FCP target, any
scsi target id value assigned to it will persist in case the
role changes back to include FCP Target. No changes in the scsi
midlayer will be invoked if the role changes (in the expectation
that the role will be resumed. If it doesn't normal error processing
will take place).
</p><p>
Should not be called from interrupt context.

This routine assumes no locks are held on entry.
