As per the general pattern for initialisation functions in iPXE, pci_init() saves code size by assuming that the caller has already zeroed the underlying storage (e.g. as part of zeroing a larger containing structure). There are several places within the code where pci_init() is deliberately used to initialise a transient struct pci_device without zeroing the entire structure, because the calling code knows that only the PCI bus:dev.fn address is required to be initialised (e.g. when reading from PCI configuration space). Ensure that using pci_init() followed by pci_read_config() will fully initialise the struct pci_device even if the caller did not previously zero the underlying storage, since Coverity reports that there are several places in the code that rely upon this.
