[SCSI] fcoe: moves common FCoE library API functions to libfcoe module
Moves these functions as-is from fcoe.c to libfcoe.c, since they're are common routines: - fcoe_wwn_from_mac - fcoe_libfc_config Signed-off-by: Vasu Dev <vasu.dev@intel.com> Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
