Michael Brown 04288974f6 [pci] Ensure that pci_read_config() initialises all fields 
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.
