    Fix pci_io_handle allocation routines.
    
    The previous version of new_io_handle()  would invalidate all previous
    allocations when realloc moves the base pointer of the ios array.
    Since I cannot figure out where this array is useful, just get rid of
    it, providing sound stable memory allocation.
    
    Fixes vgaHWSaveFonts() in 1.12 xserver on OpenBSD, but other
    sub-systems relaying on pci_io could be affected too.
