PCI: tegra: Fix return value check of pm_runtime_get_sync()
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: da76ba50963b ("PCI: tegra: Add power management support")
