    firewire: ohci: initialize page array to use alloc_pages_bulk() correctly

    The call of alloc_pages_bulk() skips to fill entries of page array when
    the entries already have values. While, 1394 OHCI PCI driver passes the
    page array without initializing. It could cause invalid state at PFN
    validation in vmap().
