nft: Expand extended error reporting to nft_cmd, too
Introduce the same embedded 'error' struct in nft_cmd and initialize it
with the current value from nft_handle. Then in preparation phase,
update nft_handle's error.lineno with the value from the current
nft_cmd.
This serves two purposes:
* Allocated batch objects (obj_update) get the right lineno value
instead of the COMMIT one.
* Any error during preparation may be reported with line number. Do this
and change the relevant fprintf() call to use nft_handle's lineno
instead of the global 'line' variable.
With this change, cryptic iptables-nft-restore error messages should
finally be gone:
| # iptables-nft-restore <<EOF
| *filter
| -A nonexist
| COMMIT
| EOF
| iptables-nft-restore: line 2 failed: No chain/target/match by that name.
