Currently, in case of station+monitor mode on KIWI target,
we are not attempting to drop the entries received in the
monitor destination ring, when no channel has been
configured for the monitor interface. This leads to the
monitor destination ring full condition and an eventual
backpressure on the ring.
Fix this issue, by dropping the entries in the monitor
destination ring, which have been received before the
monitor channel has been configured.
