Subject: [PATCH] drm/amdgpu: fix an amdgpu_irq_put() issue in gmc_v9_0_hw_fini()

As made mention of, in commit 9128e6babf10 ("drm/amdgpu: fix
amdgpu_irq_put call trace in gmc_v10_0_hw_fini") and commit c094b8923bdd
("drm/amdgpu: fix amdgpu_irq_put call trace in gmc_v11_0_hw_fini"). It
is meaningless to call amdgpu_irq_put() for gmc.ecc_irq. So, remove it
from gmc_v9_0_hw_fini().
