mlxcx_cq_setup() doesn't take required locks for ASSERTs
On debug, a user saw a panic occur in
mlxcx_arm_cq() because they didn't have the
mlcq_arm_mtx lock held. This only really blows up on debug builds. The reason that this happens and isn't so bad is that the setup code path didn't grab the muetx that was added for this purpose. However, all the code paths that matter once the device is up, are doing so.
I put together a patch and they confirmed that it fixed the problem that they had.
