Subject: [PATCH] drm/lima/lima_drv: Add missing unwind goto in lima_pdev_probe()

Smatch reports:
drivers/gpu/drm/lima/lima_drv.c:396 lima_pdev_probe() warn:
	missing unwind goto?

Store return value in err and goto 'err_out0' which has
lima_sched_slab_fini() before returning.

Fixes: a1d2a6339961 ("drm/lima: driver for ARM Mali4xx GPUs")
