[ Upstream commit 19326006a21da26532d982254677c892dae8f29b ]

Tegra194 PCIe probe path is taking failure path in success case for
Endpoint mode. Return success from the switch case instead of going
into the failure path.

Fixes: c57247f940e8 ("PCI: tegra: Add support for PCIe endpoint mode in Tegra194")
