Fix error message if PS connection is lost while receiving prefetch (#…
…9923) If the pageserver connection is lost while receiving the prefetch request, the prefetch queue is cleared. The error message prints the values from the prefetch slot, but because the slot was already cleared, they're all zeros: LOG: [NEON_SMGR] [shard 0] No response from reading prefetch entry 0: 0/0/0.0 block 0. This can be caused by a concurrent disconnect To fix, make local copies of the values. In the passing, also add a sanity check that if the receive() call succeeds, the prefetch slot is still intact.
