ice: sleep, don't busy-wait, in the SQ send retry loop
10 ms is a lot of time to spend busy-waiting. Sleeping is clearly
allowed here, because we have just returned from ice_sq_send_cmd(),
which takes a mutex.
On kernels with HZ=100, this msleep may be twice as long, but I don't
think it matters.
I did not actually observe any retries happening here.
