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

Browse source

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.
