nf_tables: fix bogus warning in nft_data_uninit()

From: Pablo Neira Ayuso <[email protected]>

From: Mirek Kratochvil <[email protected]>

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

Based on patch from Mirek.

I'm sending a v2 of this patch:

http://patchwork.ozlabs.org/patch/465960/

It doesn't apply cleanly to the nf tree and I have adjusted the indentation. If no objections, I'll apply this to the nf tree. Thanks.

Just for the record: I'll mangle this to restore your original authorship before applying, that was my intention.
