wifi: mt76: fix 6GHz high channel not be scanned

Browse Source 
[ Upstream commit 23792cedaff02351b57bddd8957fc917fa88f2e0 ]

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.
