spi: tegra210-quad: Fix missin IRQ check in tegra_qspi_probe
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.
