Btrfs: deal with io_tree->mapping being NULL
I need to add infrastructure to allocate dummy extent buffers for running sanity tests, and to do this I need to not have to worry about having an address_mapping for an io_tree, so just fix up the places where we assume that all io_tree's have a non-NULL ->mapping.
