rocker: zero allocate ports array 

When allocating the array of rocker port pointers, zero the array values so
we can test for !NULL to see if port is allocated/registered.  We'll need
this later when installing untagged VLAN support for each port, during port
probe.  It's a long story, but to install a VLAN (vid=0 for untagged, in
this case) on a port, we'll need to scan other ports to see if the VLAN
group for that VLAN has been setup.  To scan the other ports, we need to
walk the port array.
