dm clone: drop redundant size checks

Browse source

The clone target already exposes both source and destination devices via
clone_iterate_devices(), so dm-table's device_area_is_invalid() helper
ensures that the mapping does not extend past either underlying block
device.

The manual comparisons between ti->len and the source/destination device
sizes in parse_source_dev() and parse_dest_dev() are therefore
redundant. Remove these checks and rely on the core validation instead.
This changes the error strings reported when the devices are too small,
but preserves the failure behaviour.
