acl-plugin: VPP-1400: VPP may crash when performing ACL modifications on applied ACLs
The partition_split() did not increment the refcount when using a mask type index,
thus subsequent modifications potentially resulted in double frees and in the best case
immediate crash, in the worst case delayed crash in another place.
Introduce the lock_mask_type_index() and call it, move the mask type index
related functions closer to the top of the file.
Make the assignment of the new mask type indices
for the tuplemerge case to use the assign_mask_type_index().
Keep some debugs in case we need to investigate this further at some point.
