[Ovmsdev] NetManTask created twice

[Stephen Casner]

The example I showed is with all your committed changes included.

I expected only one NetManTask at a time, but I did not realize it
would be stopped and restarted.  It would be nice to know what memory
is allocated but not freed.  It may not be leaked if it is for
resources that are used by other tasks, but still it would be nice to
have all the memory properly accounted for.

Below is my startup sequence.  This may be AP auto-starting and then
stopping, followed by client mode starting from my script.  Without
the modem running, there might be no interfaces up between those two
operations.
