[PATCH] qemu-kvm: Fix assigned device config space

[Sheng Yang <sheng@linux.intel.com>]

The new pci_dev->dev.config is a uint_8 pointer, but get_real_device()
still using sizeof(pci_dev->dev.config) to fill the configuration space,
which lost most of information.

Spot the issue when INTx cannot work again after previous fix...
