If a device reports no media is present, don't try to get the geometry anyway.

Browse Source 
This confused some USB card readers, that would stop working if you still
requested the geometry when they reported no media.
Note the case that the B_GET_MEDIA_STATUS fails (because it's not implemented or
an error occured) is still handeld in _GetMediaStatus() and then we still try to
get the geometry to check for media presence.
This should fix that some USB card readers wouldn't work and should also remove
the wrongly reported size in DriveSetup for CD drives that don't actually contain
a media.
