[PATCH 5.10 17/22] drm/amdgpu: fix gart.bo pin_count leak

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Leslie Shi <Yuliang.Shi@amd.com>

[ Upstream commit 66805763a97f8f7bdf742fc0851d85c02ed9411f ]

gmc_v{9,10}_0_gart_disable() isn't called matched with
correspoding gart_enbale function in SRIOV case. This will
lead to gart.bo pin_count leak on driver unload.
