Subject: [PATCH] drm/amdgpu/virt: remove redundant variable pf2vf_ver

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable pf2vf_ver is assigned but never read, it is redundant and hence can be removed.

Cleans up clang warning:
drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c:310:3: warning: Value stored to 'pf2vf_ver' is never read
