Subject: USB: ipaq.c: fix a timeout loop

From: Dan Carpenter <dan.carpenter@oracle.com>

commit abdc9a3b4bac97add99e1d77dc6d28623afe682b upstream.

The code expects the loop to end with "retries" set to zero but, because
it is a post-op, it will end set to -1.  I have fixed this by moving the
decrement inside the loop.
