drm: Release resources with a safer function
We should use 'ida_simple_remove()' instead of 'ida_remove()' when freeing
resources allocated with 'ida_simple_get()'.
This as been spotted with the following coccinelle script which tries to
detect missing 'ida_simple_remove()' call in error handling paths.
