[media] rc: img-ir: fix error in parameters passed to irq_free()

[ Upstream commit 80ccf4ad ]

img_ir_remove() passes a pointer to the ISR function as the 2nd
parameter to irq_free() instead of a pointer to the device data
structure.
This issue causes unloading img-ir module to fail with the below
warning after building and loading img-ir as a module.
