Add a simple scope-based helper to put an inode reference, similar to
the fput() helper.

Cleaning up inode references with scope-based cleanup seems dangerous
to me because, unlike most resources, holding a reference to an inode
beyond the lifetime of the associated superblock can actually cause
memory corruption; and scope-based cleanup is designed based on the
idea that the order and precise location of dropping a reference don't
matter so much.

That's in general a good point and I know there's been opposition to
this in the past when we discussed this. So fine by me.
