Btrfs: fix tree log remove space corner case
The tree log stuff can have allocated space that we end up having split across a bitmap and a real extent. The free space code does not deal with this, it assumes that if it finds an extent or bitmap entry that the entire range must fall within the entry it finds. This isn't necessarily the case, so rework the remove function so it can handle this case properly. This fixed two panics the user hit, first in the case where the space was initially in a bitmap and then in an extent entry, and then the reverse case.
