netfilter: nftables: add nft_parse_register_load() and use it
[ Upstream commit 4f16d25c68ec844299a4df6ecbb0234eaf88a935 ]
This new function combines the netlink register attribute parser
and the load validation function.
This update requires to replace:
enum nft_registers sreg:8;
in many of the expression private areas otherwise compiler complains
with:
error: cannot take address of bit-field ‘sreg’
when passing the register field as reference.
