Snapshot creation fails when the same volume is mounted on multiple mount points of the same host

Snapshot creation fails when the same volume is mounted on multiple mount points of the same host.

For example, when the volume f3170-7-15:/vol/sample1 is mounted on the mount points /sample1 on f3170-7-15:/vol/sample1 rsize=32768,wsize=32768,NFSv3,dev=4000033 and /test1 on f3170-7-15:/vol/sample1 rsize=32768,wsize=32768,NFSv3,dev=4000034 snapshot creation fails with the following error.

mount: f3170-7-15:/vol/sample1 is not mounted on /test1

The backup of NFS share mounted by two different mount points for OST_FIM is not supported in this release.
