btrfs: directly grab inode at __btrfs_debug_check_extent_io_range()

We've tested that we are dealing with io tree that is associated to an
inode (its owner is IO_TREE_INODE_IO), so there's no need to call
btrfs_extent_io_tree_to_inode() in a separate line and we just assign
tree->inode to the local inode variable when we declare it.
