pci: Merge pci_nic_init() into pci_nic_init_nofail()
The error reporting in pci_nic_init() is quite erratic: Some errors
are printed directly with error_report(), and some are passed back
to the caller pci_nic_init_nofail() via an Error pointer.
Since pci_nic_init() is only used by pci_nic_init_nofail(), the
functions can be simply merged to clean up this inconsistency.
