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.

Fixes: bd4a633b6f7c ("block: move the nonrot flag to queue_limits")
