When loop was made down explicitly due to cable pull, then for N2N
toplogy, if FAWWPN BIT is enabled by user, then it would restore some
default(garbage) value for Physical port WWPN, so this show garbage
WWPN for the port. Fix is, to restore phsical port WWPN, if it is fabric
configuration. When loop is explicitly made down, and FAWWPN feature is
enabled, then driver need to restore original flashed WWPN.
