[PATCH] xf86drm: remove to open the DRM device unnecessarily

Seems like I'm either too subtle and/or too stingy earlier.

If drmAvailable() returns false, we have two options:
 - opt for the old-schoold (dri1) and ask drm_server_info to load the
module for us, or
 - bail out, as neither drmOpenByBusid() or drmOpenByName() will be
able to open the device considering that a DRM module is not loaded.

So what I was hinting earlier was to make the above more obvious,
rather than reordering the arguments in the if clause. How does that
sound ?
