Subject: [PATCH 3/9] Fix the faulty check of parameters in
 server_c.c:control_getcmd()

The check of the array size in server_c.c:control_getcmd() is wrong
as the nparmas is incremeted after the check with MAX_GETCMD_PARAMS.
Also, there are other bugs that *nparams isn't initialized when the
first token is NULL, etc.  Overall, the code is unnecessarily tricky.

This patch simplifies the code and fixes the array size check.
