[c-nsp] Adjusting TCAM allocation weird behavior on 7600

[Rod James Bio]

This is what I tried,

#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
  IPv4 + MPLS         - 512k (default)
  IPv6 + IP Multicast - 256k (default)

User configured :-
---------------
  IPv4 + MPLS         - 768k (default)
  IPv6                - 100k
  IP Multicast        - 28k

After a wr mem and reboot this is what I got:
*Aug  6 02:15:46.975 PHT: %MLSCEF-SP-1-MAX_ROUTE_MISMATCH: Maximum 
routes config mismatch. Reconfigure the maximum routes values and reload 
the box.

As you will see the max routes adds to 1024k but still It resets to the 
default values.
