linux-cp: fix setting mtu on hardware interfaces

Browse Source 
Type: fix
Fixes: 616447c392

In lcp_router_link_mtu(), either vnet_hw_interface_set_mtu() or
vnet_sw_interface_set_mtu() is called, based on whether this appears to
be a physical interface. The test to determine whether this is true was
incorrect and probably never worked right so vnet_sw_interface_set_mtu()
was always being called. This causes some breakage with Recent changes
to code which manages interface MTUs. Fix the test so the right function
is called.
