hv: delete vmbus_get_debug_info()
It's only used once, only contains 2 function calls, so just make those calls directly, deleting the function, and the now unneeded structure entirely. Tested-by: "K. Y. Srinivasan" <kys@microsoft.com> Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
