Wait, taking it back...

Can you make nvme_rdma_queue_sig_limit() return a bool instead?

Also, Looking at this closer, I'm pretty convinced that this
should convert to atomic. For iSER its fine as is because
we are under the iscsi connection lock, but here we need to
handle mutual exclusion.

This would be an incremental change though.
