VOP_LOCK1() (and so VOP_LOCK()) and VOP_UNLOCK() are only used in

conjuction with 'thread' argument passing which is always curthread.
Remove the unuseful extra-argument and pass explicitly curthread to lower
layer functions, when necessary.

KPI results broken by this change, which should affect several ports, so
version bumping and manpage update will be further committed.
