The nonnull attribute is not applicable to parameters that are passed by reference, at least not in the Intel compiler. Let us remove the reference indirection, which was only there so that the pointer could be assigned to NULL, and let the callers perform that task. row_log_allocate(): Fix a bug in out-of-memory error handling that would leave a pointer to freed memory.
