forcedeth: fix race when unloading module
When forcedeth module is unloaded, there exists a path that can lead
to mod_timer() after del_timer_sync(), causing an oops. This patch
short-circuits this unneeded path, which originates in
nv_get_ethtool_stats().
Tested:
x86_64 16-way + 3 ethtool -S infinite loops + 100Mbps incoming traffic
+ rmmod/modprobe/ifconfig in a loop
