Laura Garcia Liebana 14e2dee099 netfilter: nft_hash: fix hash overflow validation
The overflow validation in the init() function establishes that the
maximum value that the hash could reach is less than U32_MAX, which is
likely to be true.

The fix detects the overflow when the maximum hash value is less than
the offset itself.
