Subject: [PATCH 2/4] net: ch9200: remove extraneous return in control_write() to propagate failures

The control_write() function sets err to -EINVAL however there 
is an incorrectly placed 'return 0' statement after it which stops 
the propogation of the error.

Fix this issue by removing the 'return 0'.
