interconnect: Show bandwidth for disabled paths as zero in debugfs

[ Upstream commit b1910c6b9983817160e04d4e87b2dc1413c5361a ]

For disabled paths the 'interconnect_summary' in debugfs currently shows
the orginally requested bandwidths. This is confusing, since the bandwidth
requests aren't active. Instead show the bandwidths for disabled
paths/requests as zero.
