The differences between iterate_iovec and iterate_kvec are minor:
* kvec callback is treated as if it returned 0
* initialization of __p is with i->iov and i->kvec resp.
which is trivially dealt with.
No code generation changes - compiler is quite capable of turning
left = ((void)(STEP), 0);
__v.iov_len -= left;
(with no accesses to left downstream) and
(void)(STEP);
into the same code.
