Hangbin Liu 4970b42d5c Revert "fib_rules: return 0 directly if an exactly same rule exists when NLM_F_EXCL not supplied" 
This reverts commit e9919a24d3.

Nathan reported the new behaviour breaks Android, as Android just add
new rules and delete old ones.

If we return 0 without adding dup rules, Android will remove the new
added rules and causing system to soft-reboot.

Fixes: e9919a24d3 ("fib_rules: return 0 directly if an exactly same rule exists when NLM_F_EXCL not supplied")
