Currently code uses only top qcow2 delta to handle decompression.
Images have compression type in the qcow2 header already set when loaded.
To support mixed compression switch to use qio->qcow2 and respective
qcow2 header so the decompression is performed with the correct type.
Remove qcow2 argume
Two problems - using wrong size type:
- process_compressed_read used blk_status_t for ret which is u8
so it can not process negative error codes and larger sizes
properly - fix this by changing it to int
- decompression fails for images with size larger than 2GB
due to wrong return type of parse_

If qcow2 file has only inactive bitmaps, we should not reset
QCOW2_AUTOCLEAR_BITMAPS bit. Bitmaps are already allocated and
we are not expected to change them.
Still reset this bit if we encounter enabled bitmap.
