Remove block number field from nbtree stack. The initial value of the nbtree stack downlink block number field recorded during an initial descent of the tree wasn't actually used. Both _bt_getstackbuf() callers overwrote the value with their own value. Remove the block number field from the stack struct, and add a child block number argument to _bt_getstackbuf() in its place. This makes the overall design of _bt_getstackbuf() clearer.
