devices: show interface rx-placement displays the wrong information (VPP-894)
show interface rx-placement somtimes displays the wrong interface names.
This happens when there exists subinterfaces in VPP.
The problem is due to the function show_interface_rx_placement_fn is calling
format_vnet_sw_if_index_name with hw_if_index instead of sw_if_index.
VPP has the concept of sw_if_index and hw_if_index. Each serves a different
purpose. When there is no subinterfaces, both hw_if_index and sw_if_index
may happen to have the same value.But don't count on it. When the API calls
for sw_if_index, we must pass the sw_if_index although the hw_if_index has
the same type which the compiler does not catch. Passing hw_if_index for an
API which requires sw_if_index may have an unpredictable result such as
described in the VPP-894 and sometimes it may even crash if the particular
index does not exist.
