[PATCH 3.11 011/208] usbnet: fix status interrupt urb handling

[Luis Henriques]

3.11.10.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <nbd at openwrt.org>

commit 52f48d0d9aaa621ffa5e08d79da99a3f8c93b848 upstream.

Since commit 7b0c5f21f348a66de495868b8df0284e8dfd6bbf
"sierra_net: keep status interrupt URB active", sierra_net triggers
status interrupt polling before the net_device is opened (in order to
properly receive the sync message response).

To be able to receive further interrupts, the interrupt urb needs to be
re-submitted, so this patch removes the bogus check for netif_running().
