From: Joe Eykholt <jeykholt@xxxxxxxxx>
While the I/O and LLD interfaces use fc_rport_libfc_priv, the
disc and rport interfaces will use fc_rport_priv, which will
be separately allocated.
Change the disc and rport usage of fc_rport_libfc_priv to fc_rport_priv.
Use #define temporarily to make both names equivalent until a
subsequent patch splits them.
