The same (arguably trivial) logic is also duplicated in xfs_defer_add.
Maybe give the helper a more generic name and use it there as well?

No need to initialize this (and all the other list_heads in the items)
as we're only adding them to the work list, but never actualy using them
as the head of a list or do list_empty checks on them.

Does this commit on it's own actually work? We add the items to
the work list, but I don't think we ever take it off without the next
patch?

So this patch moves the intent structures off the stack, and the next
one then renames it to work. Maybe do the renames here so that we don't
have to touch every single use of them twice?
Otherwise this looks nice, and I really like the better structure of
the recovery code that this is leading towards.
