Fix W=1 warning. One variable is only used in a conditionally-compiled
block, mark as __maybe_unused

sound/pci/echoaudio/echoaudio.c: In function ‘snd_echo_probe’:
sound/pci/echoaudio/echoaudio.c:1958:6: warning: variable ‘i’ set but
not used [-Wunused-but-set-variable]
 1958 |  int i, err;
      |      ^
