drm/xe: Don't disable GuCRC in suspend path

Browse Source 
GuCRC should not be disabled in xe_guc_stop_prepare() as C6 is a
prerequisite for s0ix and s2idle. This is a regression caused by
the patch below.

Closes: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/7510
Fixes: 40a684f91d ("drm/xe: Decouple GuC RC code from xe_guc_pc")
