btrfs: add assertions for tree == inode->io_tree to extent IO helpers

Browse source 
Add assertions to all helpers that get tree as argument and verify that
it's the same that can be obtained from the inode or from its pages. In
followup patches the redundant arguments and assertions will be removed
one by one.
