[Patch] make "net ads changetrustpw" not abort

[Jay Fenlason]

On Fedora Core 3, or other systems where free()ing a static array
causes an abort, "net ads changetrustpw" aborts.  I checked the other
places where generate_random_str() is called, and none of them attempt
to free the static buffer it returns.

This patch fixes it:
