Fix L2FIB learn counter and memory cleanup of mac_by_ip6 hash table
Fix global_learn_count to be incremented or decremented by add and
deletion of non-static MAC entries from L2FIB only. Without this fix,
the counter may reach the threshold of 1M and stop MAC leanring even
though number of MAC entries in L2FIB is less than the threshold.
Cleanup indirect hash key memory used by mac_by_ip6 hash table on
BD deletion.
