[SCSI] libfc: Move libfc_init and libfc_exit to fc_libfc.c

Browse source 
These routines are for the libfc kernel module and should be in
the libfc .c file.

Moving the libfc __init routine into fc_libfc.c caused the creation
of the fc_setup_fcp() and fc_destroy_fcp() routines so that
scsi_pkt_cachep was not exposed outside of fc_fcp.c.
