Subject: [PATCH] NFC: netlink.c: local variables should not be exposed globally

The variable ''nfc_genl_family' is only referenced in this file and
should be marked static to prevent it from being exposed globally.

Quites the sparse warning:

warning: symbol 'nfc_genl_family' was not declared. Should it be static?
