In order to allow the remove MMU callbacks to free the RB nodes, it is necessary to prevent any references to the nodes after the remove callback has been called. Therefore, remove the node from the tree prior to calling the callback. In other words, the MMU/RB API now guarantees that all RB node operations it performs will be done prior to calling the remove callback and that the RB node will not be touched afterwards.
