USB: Fix throttling in generic usbserial driver
The generic usbserial driver in Linux 2.6.31 halts its receiving channel in response to throttle requests from the line discipline. Unfortunately it drops the contents of the first URB received after throttling takes effect. This patch corrects that problem.
