mwifiex: disable channel filtering feature in firmware 

As 2.4Ghz channels are overlapping, sometimes AP responds to
probe request even if it's operating on neighbouring channel.
Currently firmware drops those scan entries, as current channel
doesn't match with APs channel.

This patch enables MWIFIEX_DISABLE_CHAN_FILT flag in scan
command to disable the feature so that better scan results
will be received in 2.4Ghz band.
