block/io: reuse bdrv_co_pwritev() for write compressed
For bdrv_pwrite_compressed() it looks like most of the code creating coroutine is duplicated in bdrv_prwv_co(). So we can just add a flag (BDRV_REQ_WRITE_COMPRESSED) and use bdrv_prwv_co() as a generic one. In the end we get coroutine oriented function for write compressed by using bdrv_co_pwritev/blk_co_pwritev with BDRV_REQ_WRITE_COMPRESSED flag.
