PCI: don't enable too many HT MSI mappings
Prakash reported that his c51-mcp51 ondie sound card doesn't work with
MSI. But if he hacks out the HT-MSI quirk, MSI works fine.
So this patch reworks the nv_msi_ht_cap_quirk(). It will now only
enable ht_msi on own its root device, avoiding enabling it on devices
following that root dev.
