drm/modes: Don't apply cmdline's rotation if it wasn't specified 

The rotation mode from cmdline shouldn't be taken into account if it
wasn't specified in the cmdline. This fixes ignored default display
orientation when display mode is given using cmdline without the
rotation being specified.

Fixes: 1bf4e09227 ("drm/modes: Allow to specify rotation and reflection on the commandline")
