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 221697fbefc21a4dc06326362c2986fb31360b47
That is 3.5
