ALSA: hda: Add IRQ check for platform_get_irq()

[ Upstream commit 8c13212443230d03ff25014514ec0d53498c0912 ]

The function hda_tegra_first_init() neglects to check the return
value after executing platform_get_irq().

hda_tegra_first_init() should check the return value (if negative
error number) for errors so as to not pass a negative value to
the devm_request_irq().

Fix it by adding a check for the return value irq_id.
