netfilter: remove unnecessary goto statement for error recovery
Usually it's a good practice to use goto statement for error recovery
when initializing the module. This approach could be an overkill if:
1) there is only one fail case;
2) success and failure use the same return statement.
For a cleaner approach, remove the unnecessary goto statement and
directly implement error recovery.
