[c-nsp] ME3600X 15.2S memory leak - Update!

[Mark Tinka]

So feedback from the ME3600X BU is that this issue is likely similar to
what Jason described earlier in this thread.

So the workaround is to disable egress ACL functionality.

Apparently, 15.5(3)S2 is supposed to be fixed, but given that our
upgrade to this code still led to a forwarding freeze, safe to say Cisco
need to put more work into this.

Just FYI, the ASR920 is not affected, or any other platform running this
code base.

The ME3600X/3800X really is an exciting box :-\...

Mark.
