usbnet: introduce usbnet_{read|write}_cmd_nopm
This patch introduces the below two helpers to prepare for solving
the usbnet runtime PM problem, which may cause some network utilities
(ifconfig, ethtool,...) touch a suspended device.
usbnet_read_cmd_nopm()
usbnet_write_cmd_nopm()
The above two helpers should be called by usbnet resume/suspend
callback to avoid deadlock.
