qcacld-3.0: Remove #ifdef FIXME_GEN6 and obsolete enums

In the function lim_msg_str(), obsolete FIXME_GEN6 compilation macro
is still present and since this compile flag is not enabled,
this function always return "" which results in incorrect logs.

Fix is to remove this obsolete compile macro and also some of the
obsolete enums.
