qemu_hotplug: Don't free the PCI device structure after hot-unplug

Browse Source 
The pciDevice structure corresponding to the device being hot-unplugged
was freed after it was "stolen" from activeList. The pointer was still
used for eg-inactive list. This patch removes the free of the structure
and frees it only if reset fails on the device.
