drm/drv: Fix potential memory leak in drm_dev_init()

drm/drv: Fix potential memory leak in drm_dev_init()

drm_dev_init() will add drm_dev_init_release() as a callback. When
drmm_add_action() failed, the release function won't be added. As the
result, the ref cnt added by device_get() in drm_dev_init() won't be put
by drm_dev_init_release(), which leads to the memleak. Use
drmm_add_action_or_reset() instead of drmm_add_action() to prevent
memleak.
