rule: netlink attribute offset is uint32_t for struct nlerr_loc

The maximum netlink message length (nlh->nlmsg_len) is uint32_t, struct
nlerr_loc stores the offset to the netlink attribute which must be
uint32_t, not uint16_t.

While at it, remove check for zero netlink attribute offset in
nft_cmd_error() which should not ever happen, likely this check was
there to prevent the uint16_t offset overflow.
