[PATCH] scsi: fix SCSI_BNX2X_FCOE dependencies and build errors

From: Randy Dunlap <rdunlap@infradead.org>

Don't enable NETDEVICES when NET is not enabled. That causes
build warnings and errors.

warning: (SCSI_CXGB3_ISCSI && SCSI_CXGB4_ISCSI && SCSI_BNX2X_FCOE) selects NETDEVICES which has unmet direct dependencies (NET)
warning: (SCSI_CXGB3_ISCSI && SCSI_CXGB4_ISCSI && SCSI_BNX2_ISCSI && SCSI_BNX2X_FCOE) selects ETHERNET which has unmet direct dependencies (NETDEVICES && NET)
warning: (SCSI_BNX2X_FCOE && LIBFCOE && TCM_QLA2XXX) selects LIBFC which has unmet direct dependencies (SCSI_LOWLEVEL && SCSI && SCSI_FC_ATTRS)

../drivers/net/ethernet/cisco/enic/enic_main.c: In function 'enic_rq_indicate_buf':
../drivers/net/ethernet/cisco/enic/enic_main.c:1077:3: error: implicit declaration of function 'skb_mark_napi_id' [-Werror=implicit-function-declaration]
../drivers/net/ethernet/cisco/enic/enic_main.c:1078:3: error: implicit declaration of function 'enic_poll_busy_polling' [-Werror=implicit-function-declaration]
