Why not use hweight here?

And this still mixes up the on-disk and in-memory flags.  I think they
really need to be separated and kept entirely separate.

e.g. rename the d_flags field to d_type in both the on-disk and
in-core inode, rename the values to XFS_DQTYPE_*, and then have a
separate u8 d_flags just in the in-core inode for just the in-core
values.
