qcow2: Fix error handling in qcow_save_vmstate

Don't assume success but pass the bdrv_pwrite return value on.

qcow2: Return 0/-errno in get_cluster_table

Switching to 0/-errno allows it to distinguish different error cases.

qcow2: Return 0/-errno in qcow2_alloc_cluster_offset

Returning 0/-errno allows it to distingush different errors classes. The
cluster offset of newly allocated clusters is now returned in the QCowL2Meta
struct.

block: Return original error codes in bdrv_pread/write

Don't assume -EIO but return the real error.

qcow2: Improve error handling in update_refcount

If update_refcount fails, try to undo any changes made so far to avoid
inconsistencies in the image file.

qcow2: Allow updating no refcounts

There's absolutely no problem with updating the refcounts of 0 clusters.
At least snapshot code is doing this and would fail once the result of
update_refcount isn't ignored any more.

qcow2: Don't ignore update_refcount return value

update_refcount can return errors that need to be handled by the callers.

qcow2: Don't ignore qcow2_alloc_clusters return value

Now that qcow2_alloc_clusters can return error codes, we must handle them in
the callers of qcow2_alloc_clusters.
