usbnet: fix deadlock in resume

A usbnet device can share a multifunction device
with a storage device. If the storage device is autoresumed
the usbnet devices also needs to be autoresumed. Allocating
memory with GFP_KERNEL can deadlock in this case.

This should go back into all kernels that have
commit 352baebd4c24489284445ab3163c74a4591f108d
That is 3.5
