wlan: clear ChannelList everywhere it is freed

In csrNeighborRoamPerformBgScan() we are seeing invalid
dereferences of the ChannelList array. To insure that
uninitialized values of ChannelList array are never
mistakenly dereferenced we need to insure that the
ChannelList pointer is cleared everywhere that ChannelList
is freed.
