memory: mtk-smi: handle positive return value for clk_bulk_prepare_enable

Function clk_bulk_prepare_enable() returns 0 for success or a negative
number for error, although the common style for the callers is to check
always for any non-zero return value (just like its implementation in
clk.h does).  Adjust the code to such coding style.
