Robert Watson 89d1d7886a Update cache flushing behavior in light of recent namecache and
access cache improvements:

- Flush just access control state on CODA_PURGEUSER, not the full
  namecache for /coda.

- When replacing a fid on a cnode as a result of, e.g.,
  reintegration after offline operation, we no longer need to
  purge the namecache entries associated with its vnode.
