plugin_net: handle cqe-mode-rx ethtool option

Browse source 
Parsing ethtool output has been broken for several years, since `ethtool -c`
started producing a line resembling `CQE mode RX: n/a  TX: n/a`.
This prevents setting any [net] coalesce= options, which log
`tuned.plugins.plugin_net: unknown coalesce parameter(s): {'CQE mode RX'}`.

Substituting `cqe-mode-rx:` for `CQE mode RX:` resolves the issue,
although there is a conflict with the `adaptive-tx` workaround
which prevents us from supporting `cqe-mode-tx` directly.
Do not attempt to address that issue as part of this change.

Fixes #726.
