qcow2: Convert qcow2_alloc_cluster_offset() into qcow2_alloc_host_offset()
qcow2_alloc_cluster_offset() takes an (unaligned) guest offset and
returns the (aligned) offset of the corresponding cluster in the qcow2
image.
In practice none of the callers need to know where the cluster starts
so this patch makes the function calculate and return the final host
offset directly. The function is also renamed accordingly.
See 388e581615 for a similar change to qcow2_get_cluster_offset().
