In cases where iov_copy() is passed with zero 'bytes' argument and a
non-zero 'offset' argument, nothing gets copied - as expected.
However no copy iterations are performed, so 'offset' is left
unaltered, leading to the final assert(offset == 0) to fail.
Instead, change the loop condition to continue as long as 'offset || bytes',
similar to other iov_* functions.
This ensures 'offset' gets zeroed (even if no actual copy is made),
unless it is beyond end of source iov - which is asserted.
