2afd4d267e fs/ntfs3: Mark inode as bad as soon as error detected in mi_enum_attr()
Extended the `mi_enum_attr()` function interface with an additional
parameter, `struct ntfs_inode *ni`, to allow marking the inode
as bad as soon as an error is detected.

If an NTFS file system is mounted to another system with different
PAGE_SIZE from the original system, log->page_size will change in
log_replay(), but log->page_{mask,bits} don't change correspondingly.
This will cause a panic because "u32 bytes = log->page_size - page_off"
will get a negative value in the later read_log_page().
