libnftables: keep evaluating until parser_max_errors
Bail out after parser_max_errors has been reached, eg.
# nft -f /tmp/errors.nft
/tmp/errors.nft:1:23-23: Error: syntax error, unexpected newline
filter input tcp dport
^
/tmp/errors.nft:2:24-26: Error: datatype mismatch, expected internet network service, expression has type Internet protocol
filter input tcp dport tcp
~~~~~~~~~ ^^^
/tmp/errors.nft:3:24-26: Error: datatype mismatch, expected internet network service, expression has type Internet protocol
filter input tcp sport udp
~~~~~~~~~ ^^^
