conf: check HOTPLUGGABLE connect flag when validating a PCI address

Browse Source 
The HOTPLUGGABLE flag is set for appropriates buses in a PCI address
set, and thnis patch updates virDomainPCIAddressFlagsCompatible() to
check the HOTPLUGGABLE flag when searching for a suitable bus/slot for
a device. No devices request HOTPLUGGABLE though (yet), so there is no
observable effect.
