Colin Ian King 1dcaf1bcae scsi: libfc: fix null pointer dereference on a null lport

[ Upstream commit 41a6bf6529 ]

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: 7414705ea4 ("libfc: Add runtime debugging with debug_logging module parameter")
