rust: block: mq: safely abstract the poll callback
cae910b 
Add a minimal poll abstraction for Rust blk-mq drivers.

Model the hardware queue context as a shared HwCtx borrow and map the
optional io_comp_batch pointer to Option<&IoCompBatch>. This keeps the
callback on borrowed data owned by blk-mq and avoids exposing raw
pointers in driver implementations.

Use a typed PollResult to represent either a completion count or a
request to stop polling, and wire the callback into the blk-mq vtable
behind HAS_POLL so existing drivers keep poll: None.

block: rnull: wire up poll queues dummy callback
9ddc4cb 
Implement the new Operations::poll callback for rnull and return a
zero-completion PollResult.

This keeps rnull's current behavior unchanged while validating that the
borrowed poll abstraction wires cleanly into a Rust blk-mq driver.
