vgsp: m101 - route guest data pages through the server walker (Tier-1 map_va_locked)
The scratch-window comment is decisive: on the shared-management VAS the
client PD0 entries built by pdb_build are NOT preserved by the server's
root migration, so every engine-visible mapping must be installed through
DMA_UPDATE_PDE_2 - the m99/m100 direct plants were invisible (same NACK
with 16381 pages 'mapped'). Route each data page through
gsp_phys_rmcall_gr_map_va_locked (same call the request pages use) and log
the per-window acceptance/refusal (server 0x1f) so the high-VA install
behavior is measured. The window pool is currently 8 windows x 32 PTEs.
