5ddb88f22e rust: block: do not use removed queue flag API 
`blk_queue_flag_set` and `blk_queue_flag_clear` was removed in favor of a
new API. This caused a build error for Rust block device abstractions.
Thus, use the new feature passing API instead of the old removed API.

The Rust block layer API was using the old queue limit API, which was just
removed. Use the new API instead.
