netlink_delinearize: Fix resource leaks

Most of the cases are basically the same: Error path fails to free the
previously allocated statement or expression. A few cases received
special treatment though:

- In netlink_parse_payload_stmt(), the leak is easily avoided by code
  reordering.

- In netlink_parse_exthdr(), there's no point in introducing a goto
  label since there is but a single affected error check.

- In netlink_parse_hash() non-error path leaked as well if sreg
  contained a concatenated expression.
