btrfs: replace btrfs_wait_tree_block_writeback by wait_on_extent_buffer_writeback

This is used in the tree-log code and is a holdover from previous
iterations of extent buffer writeback.  We can simply use
wait_on_extent_buffer_writeback here, and remove
btrfs_wait_tree_block_writeback completely as it's equivalent (waiting
on page write writeback).
