[SCSI] fcoe, libfc: add get_lesb() to allow LLD to fill the link error status block (LESB)

Browse Source 
Add a member function pointer as get_lesb to libfc_function_template so LLD
can fill the LESB based on its own statistics. For fcoe, it fills the LESB
as a fcoe_fc_els_lesb struct according to FC-BB-5.
