fib: remove unnecessary input parameters in fib_default_rule_add

When fib_default_rule_add is invoked, the value of the input parameter
'flags' is always 0. Rules uses kzalloc to allocate memory, so 'flags' has
been initialized to 0. Therefore, remove the input parameter 'flags' in
fib_default_rule_add.
