The commit mentioned below has split the parameters of ICOSQ and async
ICOSQ, but it contained a typo: the CQ parameters were swapped for ICOSQ
and async ICOSQ. Async ICOSQ is longer than the normal ICOSQ, and the CQ
size must be the same as the size of the corresponding SQ, but due to
this bug, the CQ of async ICOSQ was much shorter than async ICOSQ
itself. It led to overflows of the CQ with such messages in dmesg, in
particular, when running multiple kTLS-offloaded streams:

mlx5_core 0000:08:00.0: cq_err_event_notifier:529:(pid 9422): CQ error
on CQN 0x406, syndrome 0x1
mlx5_core 0000:08:00.0 eth2: mlx5e_cq_error_event: cqn=0x000406
event=0x04

This commit fixes the issue by using the corresponding parameters for
ICOSQ and async ICOSQ.
