drm/panthor: Don't add write fences to the shared BOs
The only user (the mesa gallium driver) is already assuming explicit
synchronization and doing the export/import dance on shared BOs. The
only reason we were registering ourselves as writers on external BOs
is because Xe, which was the reference back when we developed Panthor,
was doing so. Turns out Xe was wrong, and we really want bookkeep on
all registered fences, so userspace can explicitly upgrade those to
read/write when needed.
