Revert "vfs: functions to change a vnode busy status and ID"

This reverts commit 8497a2cc28.

The VFS layer is not at all ready for this. Many places in the
code implicitly assume ino_t values will never change. This
functionality is only necessary for live shrinking of partitions,
which is a feature niche enough we do not need to worry about
implementing it in the first round of resizing (if ever.)
