ctrl_cmd_parse: Make coverity FORWARD_NULL happy
The 'strtok_r' function requires passing a NULL as the first parameter
on subsequent calls in order to ensure the code picks up where it left
off on a previous call. However, Coverity doesn't quite realize this
and points out that if a NULL was passed in as the third argument it
would result in a possible NULL deref because the strtok_r function will
assign the third argument to the first in the call is NULL.

Fixes: Coverity CID 135186
