swresample/rematrix: handle 22.2 as a 9 channel layout
This is as far as 22.2 follows the same channel order as
WaveFormatExtensible's channel mask (and the AV_CH_* defines).
After LFE2 the side channels would follow, but that offset of
one stops us from utilizing them without further tweaks.
This change was verified by using swresample to downmix to 5.1,
and then feeding that to WASAPI.
