erofs: fix uninitialized page cache reported by KMSAN
syzbot reports a KMSAN reproducer [1] which generates a crafted
filesystem image and causes IMA to read uninitialized page cache.
Later, (rq->outputsize > rq->inputsize) will be formally supported
after either large uncompressed pclusters (> block size) or big
lclusters are landed. However, currently there is no way to generate
such filesystems by using mkfs.erofs.
Thus, let's mark this condition as unsupported for now.
