  Log Message:
  -----------
  dpctl: Fix jump through wild pointer in "dpctl/help".

dpctl_unixctl_handler() didn't fully initialize the dpctl_params structure
it passed to the handler, which meant that dpctl_help() could see a nonnull
(indeterminate) 'usage' pointer and jump through it, causes a crash.
This commit fixes the crash by fully initializing the structure.

The dpctl/help command wasn't going to do anything useful anyway, so this
commit also stops registering it.
