[PATCH] media: tegra-video: tegra210: ensure PHY is disabled in pg_mode stop path

tegra210_csi_port_start_streaming() enables the CSI PHY regardless
of pg_mode, but tegra210_csi_port_stop_streaming() skips disabling
the PHY when pg_mode is set due to an early return.

Remove the early return so that the PHY disable path is always
executed, ensuring consistent teardown.
