v2: don't modify entry->id.device
In most cases we only use ARI with SR-IOV VFs, which do not support
INTx and therefore never hit this problem. However, some non-SR-IOV
implementations create multiple PFs, extending beyond the standard
3-bit function numbers with ARI, and do support INTx for those
additional functions. This can happen with Solarflare SFC9120
adapters. The host driver typically doesn't use INTx, so we also
haven't noticed this problem on bare metal, but when we attempt to
assign the device to a VM using vfio-pci, we fail trying to setup
default INTx signaling. Thanks,
Alex
