[PATCH] system/vl: Use global &bdo_queue in configure_blockdev()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Commit d11bf9bf0f ("vl: Factor configure_blockdev() out of main()")
passed &bdo_queue as argument, but this isn't really necessary since
there is only one call, so we still use the global variable.

Dropping the &bdo_queue argument allows to silence this global shadow
warning:

  softmmu/vl.c:678:54: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
  static void configure_blockdev(BlockdevOptionsQueue *bdo_queue,
                                                       ^
  softmmu/vl.c:172:29: note: previous declaration is here
  static BlockdevOptionsQueue bdo_queue = QSIMPLEQ_HEAD_INITIALIZER(bdo_queue);
                              ^

Remove a spurious empty line.
