[PATCH] remoteproc: qcom_q6v5_mss: Fix missing PDM subdev cleanup on probe failure

[Anup Vishwakarma]

q6v5_probe() calls qcom_add_pdm_subdev() but the remove_subdevs:
error unwind never calls qcom_remove_pdm_subdev(). If
qcom_add_sysmon_subdev() or rproc_add() subsequently fails, the PDM
subdev remains registered in the rproc subdev list.

The three sibling drivers (qcom_q6v5_adsp.c, qcom_q6v5_pas.c,
qcom_q6v5_wcss.c) all correctly call qcom_remove_pdm_subdev() in
their probe error unwind. Add the missing call after
qcom_remove_ssr_subdev(), in reverse order of registration.

Fixes: 5b9f51b200dc ("remoteproc: qcom: enable in-kernel PD mapper")
