[SCSI] libfc, fcoe: normalize format specifies for world wide names

Print all world wide node names (node, port and fabric) with the same
format specifier of "%16.16llx".  That makes sure they all print as a
16 character hex string, with lower case letters, no 0x prefix, and
without stripping off any leading 0s.
