drm/xe/multi_queue: skip submit when primary queue is suspended
Return early in submit path when the multi-queue primary exec
queue is suspended to avoid submitting while suspended.
v2: Remove idle_skip_suspend fix as that feature is being
reverted here https://patchwork.freedesktop.org/series/167262/
Fixes: bc5775c59258 ("drm/xe/multi_queue: Add GuC interface for multi queue support")
