wlan: NULL pointer access in wlan_hdd_free_cache_channels
original_channels in hdd context is getting allocated when
set disable channel command is issued and getting freed in
wlan_hdd_free_cache_channels from hdd_wlan_exit api.
When wlan_hdd_free_cache_channels api is invoked from
hdd_wlan_exit api without invoking set disable channel command,
it tries to access the "original_channels" pointer which is not
allocated and it leads to NULL pointer access.
To fix this issue, add a check to validate "original_channels"
pointer in wlan_hdd_free_cache_channels api before accessing it.
