Currently, only MTUs of VLs 0-7 are checked when calculating the maximum VL
MTU which is used to set the port MTU capability in DCC_CFG_PORT_CONFIG CSR
This can cause a port MTU capability to be set to 0 if MTUs of VLs 0-7 is 0
This would affect the VL15 traffic.

remaining on the sync_fence is racy since fence->status may have been
decremented to 0 on another CPU before fence_check_cb_func() has
