3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Brandt <chris.brandt@renesas.com>

commit dd14a3e9b92ac6f0918054f9e3477438760a4fa6 upstream.

The timeout for BULK packets was 300ms which is a long time if other
endpoints or devices are waiting for their turn. Changing it to 50ms
greatly increased the overall performance for multi-endpoint devices.
