src: make hash seed attribute optional
The hash expression requires a seed attribute to call the jhash
operation, eg.
# nft add rule x y meta mark set jhash ip saddr . ip daddr mod 2 \
seed 0xdeadbeef
With this patch the seed attribute is optional and it's generated by a
random function from userspace, eg.
# nft add rule x y meta mark set jhash ip saddr . ip daddr mod 2
The kernel will take care of generate a random seed.
