mm 8da817e6eb Disable VFS_HOLD placed on mnt_vnodecovered during the mount of a snapshot
and VFS_RELE on a non-existing hold on snapshot parent's z_vfs.

This disables the changes from OpenSolaris onnv-revision 9234:bffdc4fc05c4
(bug IDs: 6792139, 6794830) - not applicable to FreeBSD.

This fixes the process hang if umounting a manually mounted snapshot.
