block: Remove unused sector-based vectored I/O
We are gradually moving away from sector-based interfaces, towards byte-based. Now that all callers of vectored I/O have been converted to use our preferred byte-based bdrv_co_p{read,write}v(), we can delete the unused bdrv_co_{read,write}v(). Furthermore, this gets rid of the signature difference between the public bdrv_co_writev() and the callback .bdrv_co_writev (the latter still exists, because some drivers still need more work before they are fully byte-based).
