3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mirek Kratochvil <exa.exa@gmail.com>

commit 960bd2c26421d321e890f1936938196ead41976f upstream.

The values 0x00000000-0xfffffeff are reserved for userspace datatype. When,
deleting set elements with maps, a bogus warning is triggered.

WARNING: CPU: 0 PID: 11133 at net/netfilter/nf_tables_api.c:4481 nft_data_uninit+0x35/0x40 [nf_tables]()

This fixes the check accordingly to enum definition in
include/linux/netfilter/nf_tables.h
