Andreas Hindborg fd764e74e5 rust: block: fix wrong usage of lockdep API 
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.

Fixes: 3253aba340 ("rust: block: introduce `kernel::block::mq` module")
