usb: chipidea: tegra: disable runtime PM on resume failure
tegra_usb_probe() enables runtime PM before resuming the device. If
pm_runtime_resume_and_get() fails, probe returns without disabling runtime
PM. The later error paths reach pm_runtime_force_suspend(), but this early
return bypasses that cleanup.
Disable runtime PM before returning the resume error. Do not use the
fail_power_off path: the failed resume did not retain a usage reference,
so its pm_runtime_put_sync_suspend() would be unbalanced.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.
