[SCSI] libfc: fix oops in point-to-point mode

In point-to-point mode, if the PLOGI to the remote port times
out, it can get deleted by the remote port module.  Since there's
no reference by the local port, lport->ptp_data points to a freed
rport, and when the local port is reset and tries to logout again,
an oops occurs in mutex_lock_nested().

Hold a reference count on the point-to-point rdata.
