[PATCH 5.17 654/772] PCI: qcom: Fix runtime PM imbalance on probe errors

[Greg Kroah-Hartman]

From: Johan Hovold <johan+linaro@xxxxxxxxxx>

commit 87d83b96c8d6c6c2d2096bd0bdba73bcf42b8ef0 upstream.

Drop the leftover pm_runtime_disable() calls from the late probe error
paths that would, for example, prevent runtime PM from being reenabled
after a probe deferral.
