ASoC: SOF: debug: Fix potential buffer overflow by snprintf()
snprintf() returns the would-be-filled size when the string overflows
the given buffer size, hence using this value may result in the buffer
overflow (although it's unrealistic).
This patch replaces with a safer version, scnprintf() for papering
over such a potential issue.
