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 65841fd5132c3941cdf5df09e70df3ed28323212
That is 3.5
