qcacld-3.0: Trim operation classes to max supported in change station

Browse source 
qcacld-2.0 to qcacld-3.0 Propagation.

Operation classes supported can be controlled by user, which can
be sent greater than the max supported operations. This results
in stack overflow in change station command.

Add check to validate operations supported param given by user
and if it exceeds max supported value, set it to max supported
value.
