erofs: get rid of `struct z_erofs_collection'

Browse source

It was incompletely introduced for deduplication between different
logical extents backed with the same pcluster.

We will have a better in-memory representation in the next release
cycle for this, as well as partial memory folios support. So get rid
of it instead.

No logic changes.
