Free some malloced memory that wasn't being freed.

As mdadm is normally a short-lived program it isn't always necessary
to free memory that was allocated, as the 'exit()' call will
automatically free everything.  But it is more obviously correct if
the 'free' is there.
So this patch add a few calls to 'free'
