Subject: [PATCH] USB: serial: sierra driver send_setup() autopm fix

This patch presents a fix for the autosuspend feature implementation in
sierra usb serial driver for function sierra_send_setup().  Because it
is possible to call sierra_send_setup() before sierra_open() or after
sierra_close() we added a get/put interface activity to assure that the
usb control can happen even when the device is autosuspended.
