====================
ethtool: module: fix a handful of small bugs

I've been poking at the locking in ethtool and it appears
that the FW flashing is not currently taking the ops lock.
Existing drivers which implement module FW flashing seem
to have their own locking, so this series doesn't actually
add the ops lock (I'll add it in net-next). But a number
of other errors have been surfaced in the process.
