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.
