Starting with 3b363d5b55 ("anv: Assume syncobj support"), we assume
syncobj support and no longer use the execbuf sync_file API directly so
there's no point in checking for it. For the one physical device check
this deletes, we can assume has_exec_fence is always true because every
kernel with syncobj support also has sync_file.
