[ofw] IBBUS - prevent IOU mgr duplicate deref on al obj h_ca

[Smith, Stan]

Hello,
  When disabling the HCA driver and there is an SRP target in the fabric, the iou manger can decrement the IOU's PDO hca refcnt count twice which leads to a IBAL ASSERT failure in ibbus.
Indicate the HCA reference is removed in iou_mgr_iou_remove() so it is not dereferenced again in free_iou_mgr().

I can commit upon your approval.

Thank you,

Stan.
