d4b18c3e (pnfs: remove GETDEVICELIST implementation) removed the
GETDEVICELIST operation from the NFS client, but left a "hole" in the
nfs4_procedures array. This caused /proc/self/mountstats to report an
operation named "51" where GETDEVICELIST used to be. This patch adds
back stubs to fix mountstats.
