[PATCH v3 4/5] qcow2: Don't require aligned offsets in qcow2_co_copy_range_from()

[Alberto Garcia]

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.
