lru_cache: introduce lc_get_cumulative()

New helper to be able to consolidate more updates
into a single transaction.
Without this, we can only grab a single refcount
on an updated element while preparing a transaction.

lc_get_cumulative - like lc_get; also finds to-be-changed elements
@lc: the lru cache to operate on
@enr: the label to look up

Unlike lc_get this also returns the element for @enr, if it is belonging to
a pending transaction, so the return values are like for lc_get(),
plus:

pointer to an element already on the "to_be_changed" list.
In this case, the cache was already marked %LC_DIRTY.

Caller needs to make sure that the pending transaction is completed,
before proceeding to actually use this element.
