Dylan Reid 6b44e7b190 block: raw_async: reject batch atomically when SQ lacks capacity ...

submit_batch_requests pushed each BatchRequest into the io_uring SQ in
turn and used `?` to bail on the first push failure.
Leaving the initial SQEs visible to the kernel — but submitter.submit()
was never called, and every other call site in this file gates submit()
behind a preceding sq.push() that now also fails on the full ring.

This could allow a guest to DoS it's own queue or worse if the buffer is
freed early.
