usbnet: smsc95xx: disable carrier check while suspending

Browse source

[ Upstream commit 7b900ead6c ]

We need to make sure, that the carrier check polling is disabled
while suspending. Otherwise we can end up with usbnet_read_cmd()
being issued when only usbnet_read_cmd_nopm() is allowed. If this
happens, read operations lock up.
