    efi_loader: make efi_disk_create_partitions a global symbol
    
    Up to now we have been using efi_disk_create_partitions() to create
    partitions for block devices that existed before starting an EFI
    application.
    
    We need to call it for block devices created by EFI
    applications at run time. The EFI application will define the
    handle for the block device and install a device path protocol
    on it. We have to use this device path as stem for the partition
    device paths.
