guest-diag: semfix_watch read64 uncached by default (stale-cache pool-pin failure)
The watcher's resolve_sem_pool read sem->page->mem->vas through a
process-lifetime cache: a transient zero captured while UVM was still
initialising the structures was served forever, the pool pin never
landed, and the second-session client hung in cudaMallocManaged
(r88 evidence: 'pool unresolved (retry)' from the watcher while the
same walk succeeded from a fresh QMP client). Cache is now opt-in.
