qcow2: Don't require aligned offsets in qcow2_co_copy_range_from()
qemu-img's convert_co_copy_range() operates at the sector level and block_copy() operates at the cluster level so this condition is always true, but it is not necessary to restrict this here, so let's leave it to the driver implementation return an error if there is any.
