drm/xe/display: Fix double mutex initialization

All of these mutexes are already initialized by the display side since
commit 3fef3e6ff86a ("drm/i915: move display mutex inits to display
code"), so the xe shouldn´t initialize them.

Fixes: 44e694958b95 ("drm/xe/display: Implement display support")
