[SCSI] fcoe: cleans up libfcoe.h and adds fcoe.h for fcoe module

Removes no where used several inline functions prefixed with skb_*
and be16_to_cpu.

Moves fcoe module specific func prototypes to fcoe.c from libfcoe.h,
moved only need for build.

Adds fcoe module header file fcoe.h and then moves fcoe module
specific fcoe_percpu_s and fcoe_softc to fcoe.h from libfcoe.h.

Moves all defines from fcoe.c to fcoe.h since now fcoe module
has its own header file fcoe.h.

[jejb: removed EXPORT_SYMBOL_GPL(fcoe_fc_crc) which caused a section mismatch]
