Pull NFS client fixes from Anna Schumaker:
 "We have a handful of stable fixes to fix kernel warnings and other
  bugs that have been around for a while. We've also found a few other
  reference counting bugs and memory leaks since the initial 4.11 pull.

  Stable Bugfixes:
   - Fix decrementing nrequests in NFS v4.2 COPY to fix kernel warnings
   - Prevent a double free in async nfs4_exchange_id()
   - Squelch a kbuild sparse complaint for xprtrdma

  Other Bugfixes:
   - Fix a typo (NFS_ATTR_FATTR_GROUP_NAME) that causes a memory leak
   - Fix a reference leak that causes kernel warnings
   - Make nfs4_cb_sv_ops static to fix a sparse warning
   - Respect a server's max size in CREATE_SESSION
   - Handle errors from nfs4_pnfs_ds_connect
   - Flexfiles layout shouldn't mark devices as unavailable"
