[PATCH v9 01/16] perf arm-spe: Refactor printing string to buffer

When outputs strings to the decoding buffer with function snprintf(), SPE decoder needs to detects if any error returns from snprintf() and if so needs to directly bail out. If snprintf() returns success, it needs to update buffer pointer and reduce the buffer length so can continue to output the
