[PATCH] drm/amdgpu: unlock on error in gfx_v9_4_3_kiq_resume()

[Dan Carpenter]

Smatch complains that we need to drop this lock before returning.

    drivers/gpu/drm/amd/amdgpu/gfx_v9_4_3.c:1838 gfx_v9_4_3_kiq_resume()
    warn: inconsistent returns 'ring->mqd_obj->tbo.base.resv'.

Fixes: 86301129698b ("drm/amdgpu: split gc v9_4_3 functionality from gc v9_0")

The Fixes tag is weird, but I think it's correct?
