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

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.
