meson_pcie_probe_clock() enables a clock and then registers a devres
action to disable it during teardown. If devm_add_action_or_reset()
fails, it runs the action immediately, disabling the clock.

The return value is currently ignored, so on that failure path
meson_pcie_probe_clock() returns the disabled clock and probe continues.
Return the error so the existing probe error path unwinds normally.
