Pull NFS client bugfixes from Trond Myklebust:
 "We've just concluded another Connectathon interoperability testing
  week, and so here are the fixes for the bugs that were discovered:

   - Don't allow NFS silly-renamed files to be deleted
   - Don't start the retransmission timer when out of socket space
   - Fix a couple of pnfs-related Oopses.
   - Fix one more NFSv4 state recovery deadlock
   - Don't loop forever when LAYOUTGET returns NFS4ERR_LAYOUTTRYLATER"
