nxm: fix nxm to OFPMatch conversion

This fixes a bug that the conversion ignores dl_dst.

Soheil Hassas Yeganeh reported a problem about simple_isolation:

The problem is that the isolation service tries to install
flow-entries for a specific src and dst (in
SimpleIsolation._modflow_and_send_packet), but instead the nx match
code installs flow-entries only with src addresses and ignores the
dst.  So, when I boot multiple vms, only one of them is reachable.

For instance, assume that you have two VM's A and B. When a packet
comes from the gw to A, it installs "gw->A: A's port", but the acutal
installed rule is "gw: A's port". This works for A, but, when you boot
B, it tries to install "gw->B: B's port", but the acutal rule to be
installed is "gw: B's port".  So, it always connect the gateway to
only one VM at a time.
