iwlwifi: abstract out missing SEQ_RX_FRAME workaround
Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround warning with a statistics notification, this means we can't just remove it as we'd hoped. Abstract it out so that the higher layer can configure this as a kind of "filter" in the transport.
