Vbox is broken for me after recent upgrade.

I just glanced at the virtualbox code for a couple minutes. For FreeBSD
9 and 10, these lock acquires are completely unnecessary, and have been
since FreeBSD 9.0. Just delete them. They may be equally unnecessary
under FreeBSD 8, but I didn't look carefully enough to answer that question.

Thank you, Alan.
I temporary commented out vm_page_lock_queues()/vm_page_unlock_queues() in "src/VBox/Runtime/r0drv/freebsd/memobj-r0drv-freebsd.c".
So far, it works!! We need to wait for official fix, but just to report that it enabled to run.

Regards,

Garrett Cooper

I'll produce a patch for this sometime this weekend if someone else
doesn't beat me to it first...
