spi: tegra114: Add missing IRQ check in tegra_spi_probe
[ Upstream commit 4f92724d4b92c024e721063f520d66e11ca4b54b ]
This func misses checking for platform_get_irq()'s call and may passes the
negative error codes to request_threaded_irq(), which takes unsigned IRQ #,
causing it to fail with -EINVAL, overriding an original error code.
Stop calling request_threaded_irq() with invalid IRQ #s.
