netdev: fix potential command ID overwrite setting CQM threshold

Browse Source 
With the introduction of affinities the CQM threshold can be toggled
by a DBus call. There was no check if there was already a pending
call which would cause the command ID to be overwritten and lose any
potential to cancel it, e.g. if netdev went down.
