David Engraf 01705a8d41 PCI: tegra: Fix return value check of pm_runtime_get_sync() ...

commit 8851991484 upstream.

pm_runtime_get_sync() returns the device's usage counter. This might
be >0 if the device is already powered up or CONFIG_PM is disabled.

Abort probe function on real error only.

Fixes: da76ba5096 ("PCI: tegra: Add power management support")
