[PATCH] target/cxgbit: add INET dependency

[Arnd Bergmann]

The newly added cxgbit driver directly calls functions of the
IPv4 network stack, which fails if that is disabled:

ERROR: "ip_route_output_flow" [drivers/target/iscsi/cxgbit/cxgbit.ko] undefined!
ERROR: "__ip_dev_find" [drivers/target/iscsi/cxgbit/cxgbit.ko] undefined!

This adds a Kconfig dependency to ensure we can't enable this
driver without the complete network stack it needs.
