ASoC: pcm6240: do not free an unrequested IRQ

Browse Source 
The driver obtains an IRQ number from device tree but never requests an
IRQ handler for the PCM6240 device.  Removing the device must not pass
that number to free_irq().

Leave IRQ ownership to a matching request path if one is added later.
