drm/i915/gvt: Drop unused helper intel_vgpu_reset_gtt()
Drop intel_vgpu_reset_gtt() as it no longer has any callers. In addition
to eliminating dead code, this eliminates the last possible scenario where
__kvmgt_protect_table_find() can be reached without holding vgpu_lock.
Requiring vgpu_lock to be held when calling __kvmgt_protect_table_find()
will allow a protecting the gfn hash with vgpu_lock without too much fuss.
No functional change intended.
