btrfs: fix buffer index in wait_eb_writebacks()

Browse Source 
The commit f2cb97ee96 ("btrfs: index buffer_tree using node size")
changed the index of buffer_tree from "start >> sectorsize_bits" to "start
>> nodesize_bits". However, the change is not applied for
wait_eb_writebacks() and caused IO failures by writing in a full zone. Use
the index properly.
