commit 82fc28fbedbb59642f05215db3b0ef4eb91aa31d upstream. By function, chunk item verification is more suitable to be done inside tree-checker. So move btrfs_check_chunk_valid() to tree-checker.c and export it. And since it's now moved to tree-checker, also add a better comment for what this function is doing.
