From: Colin Ian King <colin.k...@canonical.com>
Currently if lport is null then the null lport pointer is dereference
when printing out debug via the FC_LPORT_DB macro. Fix this by using
the more generic FC_LIBFC_DBG debug macro instead that does not use
lport.
Addresses-Coverity: ("Dereference after null check")
Fixes: 7414705ea4ae ("libfc: Add runtime debugging with debug_logging module
parameter")
