Fix: param-validation: remove memory leaks

The GArray allocated in bt_param_validation_validate is never freed, fix
that.  Furthermore, there's a spurious call to
g_ptr_array_new_with_free_func that shouldn't be there, probably the
result of a bad merge or bad edit, causing another leak.  Remove that
one.
