[f-nsp] NP egress buffer on CES

[Gerald K.]

I see similar messages on our old CER2024 gear, even when the 2x10G
interfaces are unused and disabled:

cer2024#sh int brie
...
2/1  Disabled None None None  None  No  level0 748e.f838.6531
2/2  Disabled None None None  None  No  level0 748e.f838.6532
...

cer2024#sh log
...
Mar 27 15:17:11:A:NP CSRAM has 13 error events, exceeding configured
threshold for interfaces 2/1 to 2/2.
Mar 27 15:07:11:A:NP CSRAM has 14 error events, exceeding configured
threshold for interfaces 2/1 to 2/2.
Mar 27 14:57:11:A:NP CSRAM has 14 error events, exceeding configured
threshold for interfaces 2/1 to 2/2.
Mar 27 14:47:11:A:NP CSRAM has 12 error events, exceeding configured
threshold for interfaces 2/1 to 2/2.
Mar 27 14:37:11:A:NP CSRAM has 12 error events, exceeding configured
threshold for interfaces 2/1 to 2/2.
