Move the announcement code to a separate function for reuse in
a forthcoming patch.

For messages regarding FCF timeout and selection, use the
previously-announced FCF MAC address (dest_addr) in the fcoe_ctlr struct.
Only print (announce) the FCF if it is new.   Print MAC for
timed-out or deselected FCFs.
