[PATCH nftables 2/4] src: parser: fix parsing of chain priority and policy on bigendian

[Florian Westphal]

tests/shell/testcases/flowtable/0001flowtable_0
tests/shell/testcases/nft-f/0008split_tables_0
fail the 'dump compare' on s390x.
The priority (10) turns to 0, and accept turned to drop.

Problem is that '$1' is a 64bit value -- then we pass the address
and import 'int' -- we then get the upper all zero bits.

Use an intermediate value instead.

Fixes: 627c451b2351 ("src: allow variables in the chain priority specification")
Fixes: dba4a9b4b5fe ("src: allow variable in chain policy")
