qcacld-3.0: do not process HT IE change if RoC is in progress

Browse Source 
qcacld-2.0 to qcacld-3.0 propagation.

Ignore HT IE change if RoC is in progress because as
part of HT IE change we will try to change the channel
parameters which use the same callback as RoC. So if
we try to change the channel parameters if RoC is in
progress we will overwrite the callback causing problems
in the upper layers which are expecting a notification.
