First patch is just some cleanup.  The second patch adds helpers for
drivers to deal with "invisible" unmapped BO locking.  Ie. a VM_BIND
ioctl won't explicitly list BOs associated with unmapped/remapped VAs
making locking all the BOs involved in a VM_BIND ioclt harder than it
needs to be.  The helpers added solves that.
