PCI: Kill pci_is_reassigndev()

Browse Source 
pci_reassigndev_resource_alignment() is the only user of
pci_is_reassigndev().  If we just use pci_specified_resource_alignment()
directly, we only need to call it once instead of twice, and we can get
rid of pci_is_reassigndev() altogether.  No functional change.
