EX-3937 lnet: include linux/ethtool.h

Commit a8929b9f0b3e86ae91fd0037edc37a356020a947 added
a check to see if linux/ethtool.h is included in
linux/netdevice.h. However, a more simple way is to
include linux/ethtool.h directly in the files that use
"struct ethtool_ops".

Test-Parameters: trivial

Fixes: a8929b9f0b3 ("EX-3937 lnet: check if ethtool.h is included in netdevice.h")
