ASoC: SOF: debug: Fix a potential issue on string buffer termination
[ Upstream commit 9037c3bde65d339017ef41d81cb58069ffc321d4 ]
The function simple_write_to_buffer() doesn't add string termination
at the end of buf, we need to handle it on our own. This change refers
to the function tokenize_input() in debug.c and the function
sof_dfsentry_trace_filter_write() in trace.c.
