netfilter: nftables: add nft_parse_register_load() and use it
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.
