pci: Replace pci_add_capability2() with pci_add_capability()

After the patch 'Make errp the last parameter of pci_add_capability()',
pci_add_capability() and pci_add_capability2() now do exactly the same.
So drop the wrapper pci_add_capability() of pci_add_capability2(), then
replace the pci_add_capability2() with pci_add_capability() everywhere.
