block-backend: convert blk_co_pwritev_part to int64_t bytes
We convert blk_do_pwritev_part() and some wrappers: blk_co_pwritev_part(), blk_co_pwritev(), blk_co_pwrite_zeroes(). All functions are converted so that the parameter type becomes wider, so all callers should be OK with it. Look at blk_do_pwritev_part() body: bytes is passed to: - trace_blk_co_pwritev (we update it here) - blk_check_byte_request, throttle_group_co_io_limits_intercept, bdrv_co_pwritev_part - all already have int64_t argument. Note that requests exceeding INT_MAX are still restricted by blk_check_byte_request().
