This fixes the panic on the vnode interlock.  The problem is that vfs_vnops.c
wasn't including sys/lock.h, so LOCK_DEBUG wasn't defined, so it wasn't getting
LOCK_DEBUG defined properly and was just inling the mutex operation and not
calling witness.  Arguably, I should cause the compile to break when mutex.h is
included w/o lock.h, but this will work for now.  Also, getting LOCK_DEBUG
right really depends on knowing the value of KTR_COMPILE which requires
including sys/ktr.h, so in theory sys/_lock.h should either include sys/ktr.h
or mandate it's inculsion in the _KERNEL case.  Bruce, do you have any
preferences on this?
