Subject: [PATCH 4.9 055/207] USB: iowarrior: fix control-message timeouts

From: Johan Hovold <johan@...nel.org>

commit 79a4479a17b83310deb0b1a2a274fe5be12d2318 upstream.

USB control-message timeouts are specified in milliseconds and should
specifically not vary with CONFIG_HZ.

Use the common control-message timeout define for the five-second
timeout and drop the driver-specific one.

Fixes: 946b960d13c1 ("USB: add driver for iowarrior devices.")
