drm/amdgpu: lock UALink import invalidation via drm_exec

Browse source

Convert amdgpu_ualink_invalidate_import_mappings() to lock the BO and
every client VM root PD in a single drm_exec transaction instead of
borrowing the caller's reservation ticket via dma_resv_locking_ctx().

drm_exec owns its ww_acquire_ctx (exec.ticket) for the lifetime of the
transaction, so amdgpu_vm_handle_moved() now uses &exec.ticket.

Also, drop the explicit dma_resv_reserve_fences call as amdgpu_vm_lock_pd()
already reserves 2 + num_fences on the same VM root PD.
