From: "K. Y. Srinivasan" <kys@microsoft.com>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit 73cffdb65e679b98893f484063462c045adcf212 upstream.

Don't wait after sending request for offers to the host. This wait is
unnecessary and simply adds 5 seconds to the boot time.
