Pull more NFS client fixes from Anna Schumaker:
 "These are mostly refcounting issues that people have found recently.
  The revert fixes a suspend recovery performance issue.

   - SUNRPC: Fix a credential refcount leak

   - Revert "SUNRPC: Declare RPC timers as TIMER_DEFERRABLE"

   - SUNRPC: Fix xps refcount imbalance on the error path

   - NFS4: Only set creation opendata if O_CREAT"
