spi: tegra: Fix a memory leak in tegra_slink_probe()

[ Upstream commit 41d9a6795b95d6ea28439ac1e9ce8c95bbca20fc ]

In tegra_slink_probe(), when platform_get_irq() fails, it directly
returns from the function with an error code, which causes a memory leak.

Replace it with a goto label to ensure proper cleanup.
