[PATCH drm-dp 04/10] drm/hisilicon/hibmc: fix the hibmc loaded failed bug

[Yongbang Shi]

From: Baihan Li <libaihan at huawei.com>

When hibmc loaded failed, the driver use hibmc_unload to free the
resource, but the mutexes in mode.config are not init, which will
access an NULL pointer.

Fixes: b3df5e65cc03 ("drm/hibmc: Drop drm_vblank_cleanup")
