Pull NFS client fixes from Anna Schumaker:
 "These patches fix a problem with compiling using an old version of
  gcc, and also fix up error handling in the SUNRPC layer.

   - NFSv4: Ensure gcc 4.4.4 can compile initialiser for
     "invalid_stateid"

   - SUNRPC: Allow connect to return EHOSTUNREACH

   - SUNRPC: Handle ENETDOWN errors"
