tracing/probes: Avoid setting TPARG_FL_FENTRY and TPARG_FL_RETURN

When parsing a kprobe event, the return probe always sets both
TPARG_FL_RETURN and TPARG_FL_FENTRY, but this is not useful because
some fetchargs are only for return probe and some others only for
function entry. Make it obviously mutual exclusive.
