    libxl: fix crash when initializing driver
    
    Commit 54a401af478 split out DriverConfigInit from DriverConfigNew, but
    then called it a bit late from libxlStateInitialize. The cfg is used in
    libxlDriverConfigLoadFile and when uninitialized results in a crash.
    Calling DriverConfigInit immediately after DriverConfigNew fixes the
    crash.
