description:
VOP_IOCTL() is a wrapper around spec_ioctl() aka Xdev_ioctl() and
protected with spec_io_enter()/spec_io_exit() so there is no need
to force specific vnode locking.

Set locking requirement to '= = =' (unchanged, locked or unlocked).

PR kern/57450 (unplugging hung USB disk triggers panic via _vstate_assert)
