btrfs: move leak debug code to functions
Clean up the leak debugging in extent_io.c by moving the debug code into functions. This also removes the list_heads used for debugging from the extent_buffer and extent_state structures when debug is not enabled. Since we need a global debug config to do that last part, implement CONFIG_BTRFS_DEBUG to accommodate. Thanks to Dave Sterba for the Kconfig bit.
