[PATCH net 1/2] MAINTAINERS: Move M Chetan Kumar to CREDITS

[Bagas Sanjaya <bagasdotme@gmail.com>]

Emails to him bounce with 550 error code:

```
5.1.0 - Unknown address error 550-'5.1.1 <m.chetan.kumar@linux.intel.com>: Recipient address rejected: User unknown in virtual mailbox table'
```

It looks like he had left Intel, so move him to CREDITS.
