Summary

This is the preparation for the precise vnode recycle on ZFS and nullfs.
In the upcoming commits, those filesystems make mnt_fsvninusep point to the
vnode counter internal in each filesystem.

This change does not affect any filesystems that do not set mnt_fsvninusep.

This change is separated from the ZFS and nullfs fixes because it modifies
struct mount.
