drm/hisilicon/hibmc: fix the hibmc loaded failed bug

Browse source

[ Upstream commit 93a08f856f ]

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. Just change goto statement to return, because
hibnc_hw_init() doesn't need to free anything.
