btrfs: use ASSERT to report logical error in cow_file_range()

Use ASSERT to report logical error in cow_file_range(), also move it a
bit closer to when the num_bytes is derived.

The extent start could be (u64)-1 in some cases, the assert should catch
that we do not accidentally pass it to cow_file_range.
