ASoC: qcom: sm8250: Fix possibly undefined reference

With CONFIG_SND_SOC_SM8250=y and CONFIG_SND_SOC_QCOM_OFFLOAD_UTILS=m
selected in kconfig, the build will fail due to trying to link against a
symbol only found in the module.

  aarch64-linux-gnu-ld: sound/soc/qcom/sm8250.o: in function `sm8250_snd_exit':
  sound/soc/qcom/sm8250.c:52:(.text+0x210): undefined reference to `qcom_snd_usb_offload_jack_remove'

Fix this by declaring the dependency that forces CONFIG_SND_SOC_SM8250=m
when CONFIG_SND_SOC_QCOM_OFFLOAD_UTILS is =m.
