Subject: [PATCH v2] clk: qcom: lpass: Correct goto target in lpass_core_sc7180_probe()

lpass_core_sc7180_probe() misses to call pm_clk_destroy() and
pm_runtime_disable() in error paths. Correct goto target to fix it.
This issue is found by code inspection.

Fixes: edab812d802d ("clk: qcom: lpass: Add support for LPASS clock controller for SC7180")
