bus/pci: fix VFIO device reset

If the device is not capable of resetting, then Linux kernel updates
the errno as EINVAL.
http://elixir.free-electrons.com/linux/v4.9/source/drivers/vfio/pci/vfio_pci.c#L887

Honor the EINVAL errno value to avoid pci vfio setup failure.

Fixes: f25f8f367644 ("bus/pci: check VFIO reset ioctl error")
