[PATCH 2/2] ASoC: qcom: x1e80100: recreate the headset jack on card rebind

[Tyler Baker]

The headset jack is only created while jack_setup is false and nothing
clears it, so after a card rebind it is not created again and the
codecs keep a pointer to the freed jack.

Clear it on link exit, as sc8280xp does.

Fixes: 6b9dc2da6657 ("ASoC: qcom: Add x1e80100 sound machine driver")
