RHEL7.1: contents of /proc/fs/nfsfs/volumes now equal to /proc/fs/nfsfs/servers

Issue

• The contents of /proc/fs/nfsfs/volumes no longer contains expected content.
• Contents of /proc/fs/nfsfs/volumes equals /proc/fs/nfsfs/servers which is incorrect

 cat /proc/fs/nfsfs/volumes
NV SERVER   PORT USE HOSTNAME
v4 c0a87a25  801   1 rhel7-nfs-server
# cat /proc/fs/nfsfs/servers
NV SERVER   PORT USE HOSTNAME
v4 c0a87a25  801   1 rhel7-nfs-server

• On RHEL7.0 kernel-3.10.0-123.el7 the expected content is seen inside /proc/fs/nfsfs/volumes

# cat /proc/fs/nfsfs/volumes
NV SERVER   PORT DEV     FSID              FSC
