drm/amdgpu: Fix GART and SDMA entity leak on vPod reconfiguration

Browse source

remote->active_accel_bits aliased info->vpod.active_accel_bits, which
psp_ual_query_info() refreshes on every commit. Teardown
(peer_remote_fini / gart unmap) then iterated the new set instead of the
one sw_init mapped, orphaning drm_mm nodes in the shared GTT manager.
Make active_accel_bits an owned snapshot copied at sw_init time. Drop the
now-redundant not-initialised guard in metadata_npa_unmapping(), since the
earlier remote->ring_bo NULL-check already covers that case.
