Subject: [PATCH next] ALSA: hda: cs35l41: Fix missing error code in cs35l41_smart_amp()

When firmware status is invalid, assign -EINVAL to ret as ret is '0' at
that point and returning success is incorrect when firmware status is
invalid.

Fixes: a51d8ba03a4f ("ALSA: hda: cs35l41: Check CSPL state after loading firmware")
