vgsp: gate the injected shared-surface pin author (default off)
The strict signature scan used to locate the shared surface can match a guest
page-table page: the same 1.4M 'refCount/lkr' values reappear at the same
offsets across VMs, and writing the lkr into it coincides with guest bad-pmd
and soft-lockup storms in unrelated processes. Keep the VAS-walk author on,
but require sema_gl_shsurf_pin=1 for the injected-pin page; only a page proven
to be the client's shared surface (release target VA resolved through a
verified VAS) should be authored.
