[PATCH 05/13] net/ntb: Use never-managed version of pci_intx()

pci_intx() is a hybrid function which can sometimes be managed through
devres. To remove this hybrid nature from pci_intx(), it is necessary to
port users to either an always-managed or a never-managed version.

hw/amd and how/intel enable their PCI-Device with pci_enable_device().
Thus, they need the never-managed version.

Replace pci_intx() with pci_intx_unmanaged().
