ip: fix fib and mfib locks
This patches fixes an issue that could cause fib locks to underflow: if an API user deletes a fib and quickly recreates it, the fib may not have been actually deleted. As a result, the lock would not be incremented on the create call leading to the fib potentially disappearing afterwards - or to the lock to underflow when the fib is deleted again. In order to keep the existing API semantics, we use the locks with API and CLI source as flags. This means we need to use a different counter for the interface-related locks. This also prevents an issue where an interface being bound to a vrf via API and released via CLI could mess up the lock counter. Finally, this will help with cleaning up the interface-related locks on interface deletion in a later patch.
