net/mlx5e: Enhance ICOSQ data on RX reporter's diagnose 

When the RQ is in striding RQ mode, it uses the ICOSQ as a helper queue.
In this mode, RX reporter dumps more info about the ICOSQ and its
related CQ.

$ devlink health diagnose pci/0000:00:0b.0 reporter rx
Common config:
    RQ:
      type: 2 stride size: 2048 size: 8
      CQ:
        stride size: 64 size: 1024
RQs:
    channel ix: 0 rqn: 2413 HW state: 1 SW state: 5 WQE counter: 7 posted WQEs: 7 cc: 7
    CQ:
      cqn: 1032 HW status: 0 ci: 0 size: 1024
    EQ:
      eqn: 7 irqn: 42 vecidx: 1 ci: 93 size: 2048
    ICOSQ:
      sqn: 2411 HW state: 1 cc: 74 pc: 74 WQE size: 128
      CQ:
        cqn: 1029 cc: 8 size: 128
    channel ix: 1 rqn: 2418 HW state: 1 SW state: 5 WQE counter: 7 posted WQEs: 7 cc: 7

    ICOSQ:

      CQ:
