scsi: libfc: fix null pointer dereference on a null lport
[ Upstream commit 41a6bf6529edd10a6def42e3b2c34a7474bcc2f5 ]
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")
