<offset> is a backing-device sector offset; ti->len is the virtual
target length. Comparing them rejects valid tables, e.g.:
dmsetup create ebs0 --table "0 1048576 ebs /dev/sda 2097152 1 8"
-> ebs: Invalid device offset sector (-EINVAL)
Drop the check. Bounds against the backing device are already
enforced later by device_area_is_invalid() via ebs_iterate_devices().
