Code Issues Proposed changes

Check for allocated or claimed PCI status in DB 

Due to the periodic update of the PCI status there is a potential when
checking the pci device status after a live-migration it may still be
claimed instead of allocated. Updated the DB query based on if sr-iov
hotplugging is enabled to check for either allocated or claimed.
