wifi: mt76: fix 6GHz high channel not be scanned
mt76 scan command only support 64 channels currently. If the channel count is larger than 64(for 2+5+6GHz), some channels will not be scanned. Hence change the scan type to full channel scan in case of the command cannot include proper list for chip.
