Kevin Wolf a99dfb45f2 qcow2: Fix qcow2_get_cluster_offset() for zero clusters ...

When searching for contiguous zero clusters, we only need to check the
cluster type. Before this patch, an increasing offset (L2E_OFFSET_MASK)
was expected, so that the function never returned more than a single
zero cluster in practice. This patch fixes it to actually return as many
contiguous zero clusters as it can.
