ASoC: Intel: avs: Make enable_logs() dependent on DEBUG_FS

Without debug filesystem present, this code is redundant.
Operations: log_buffer_status and log_buffer_offset are left as is as
EXCEPTION_CAUGHT and even unexpected LOG_BUFFER_STATUS notifications may
occur without user ever touching debugfs.
