[PATCH v2 5/5] media: iris: Free the interrupt in iris_remove()

[Vishnu Reddy <busanna.reddy@oss.qualcomm.com>]

The interrupt is requested with devm_request_threaded_irq(), so it is
only freed after iris_remove() returns. Until then the threaded handler
can still run while the rest of the removal is in progress.

Free the interrupt explicitly in iris_remove(), right after the core is
shut down.
