Do not chown mounted filesystems
Do not chown mounted filesystems

This fixes the condition where the nfsv3driver process fails and cannot
be restarted.  This happens when the nfsv3driver.cell_mount_path already
exists and has mounts under it, and then tries to chown everything under
it to cvcap:cvcap, which probably doesn't exist on the remote systems.

This is fixed by simply removing the recursive flag (-R) from the chown
command.  There should be no negative impact by this change because
everything under this path is a remote mount.
