be2net: don't rearm mcc cq when device is not open
When an MCC cmd is issued (via a netdev/ethtool op)
while the device is not open, the MCC CQ gets processed but the EQ
is not processed (as isr is not registered.) This can cause the EQ
to become full. So, while the device is not open, CQ must not be re-armed
to prevent EQ entries.
