[SCSI] fcoe, libfc: fix double fcoe_softc memory alloc

The foce_softc mem was reserved by libfc_host_alloc as well as
by fcoe_host_alloc.

Removes one liner fcoe_host_alloc completely, instead directly calls
libfc_host_alloc to alloc scsi_host with libfc for just one fcoe_softc
as fcoe private data.

Moves libfc_host_alloc to libfc.h since it is a libfc API, placed
lport_priv API adjacent to libfc_host_alloc since this is related
to scsi_host priv data.
