Prefer secondary bus reset over FLR

Please test the attached patch against a recent Linux kernel tree on the host. 
This will cause the reset function interface to prefer a secondary bus reset
over FLR for this device, which should resolve both the 'echo 1 > reset'
failure and the assignment to QEMU using vfio-pci.  If you prefer a different
reporting/testing attribute in the patch, please let me know and I'll correct
it before posting upstream, assuming this works.
