qcacld-3.0: Correctly document wma_tx_packet()

Currently the prototype and the implementation of wma_tx_packet() use
different identifiers for some of the parameters, which is confusing
to both programmers and to tools. In addition currently the
implementation is documented instead of the interface. Therefore move
the documentation to the header file, and changed the prototype to
match the implementation.
