For both updated functions, the type of bytes becomes wider, so all callers
should be OK with it.
blk_co_preadv() only passes its arguments to blk_do_preadv().
blk_do_preadv() passes bytes to:
- trace_blk_co_preadv, which is updated too
- blk_check_byte_request, throttle_group_co_io_limits_intercept,
bdrv_co_preadv, which are already int64_t.
Note that requests exceeding INT_MAX are still restricted by
blk_check_byte_request().
