erofs: enable sub-page compressed block support
Let's just disable cached decompression and inplace I/Os for partial
pages as the first step in order to enable sub-page block initial
support. In other words, currently it works primarily based on
temporary short-lived pages. Don't expect too much in terms of
performance.
