In addition to ext4_find_extent reading extent block return
-EIO, ext4_handle_error will be called when there is a problem that
may cause file system inconsistency in the ext4_ext_insert_extent
function.
So call the ext4_handle_error function when the ext4_find_extent
read fails，and make the filesystem read-only when mount for
`errors=remount-ro`, and Check whether the journal is aborted in
the ext4_split_extent_at function.
