Vnode state, lock and fstrans cleanup:
- Rename vnode state "VS_ACTIVE" to "VS_LOADED" and add synthetic
  state "VS_ACTIVE" to assert a loaded vnode with usecount > 0.

- Redo FSTRANS in vnode_if.c and use it for VOP_LOCK and VOP_UNLOCK.

- Cleanup the genfs lock operations.

- Make "struct vnode_impl" member "vi_lock" a krwlock_t again.

- Remove the lock type argument from fstrans_start and
  fstrans_start_nowait,
  remove now unused FSTRANS state "FSTRANS_SUSPENDING".
