Some comments in Rust files use raw URLs (http://example.com) rather
than Markdown autolinks <URL>. This inconsistency makes the
documentation less uniform and harder to maintain.
This patch converts all remaining raw URLs in Rust code comments to use
the Markdown autolink format, maintaining consistency with the rest of
the codebase which already uses this style.

Align bullet points and improve indentation in the `Invariants` section
of the `GenDisk` struct documentation for better readability.
[ Yutaro is also working on implementing the lint we suggested to catch
this sort of issue in upstream Rust:

`Result` is used in place of `Result<()>` because the default type
parameters are unit `()` and `Error` types, which are automatically
inferred. Thus keep the usage consistent throughout codebase.

When allocating `struct gendisk`, `GenDiskBuilder` is using a dynamic
lock class key without registering the key. This is an incorrect use of
the API, which causes a `WARN` trace.
Fix the issue by using a static lock class key, which is more appropriate
for the situation anyway.

`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.
