[RFC 26/34] drm/xe: VMs don't need the mem_access protection anymore

[Rodrigo Vivi]

All the VM operations are now protected or by the IOCTL
calls, or by sched/exec operations or by the specific
xe_pm_runtime_{get,put} around the duration of the LR VMs.

So, these inner mem_access protections can be removed.
