media: venus: hfi: explicitly release IRQ during teardown
[ Upstream commit 640803003cd903cea73dc6a86bf6963e238e2b3f ]
Ensure the IRQ is disabled - and all pending handlers completed - before
dismantling the interrupt routing and clearing related pointers.
This prevents any possibility of the interrupt triggering after the
handler context has been invalidated.
Fixes: d96d3f30c0f2 ("[media] media: venus: hfi: add Venus HFI files")
