Konstantin Belousov de27805fee linuxkpi: handle ARI
Stop trying to manually calculate RID, which cannot be done correctly
by PCI_DEVFN().  Use PCI_GET_RID() method instead.

Do not use pci_find_dbsf() to go from the linux pci_dev to freebsd
device_t.  First, device is readily available as dev.bsddev.  Second,
using pci_find_dbsf() fails for ARI-enabled functions with large
function numbers, because PCI_SLOT()/PCI_FUNC() are for non-ARI.
