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().
