Dan Carpenter c3f4f4547f sh: intc: Fix use-after-free bug in register_intc_controller() 
[ Upstream commit 63e72e5519 ]

In the error handling for this function, d is freed without ever
removing it from intc_list which would lead to a use after free.
To fix this, let's only add it to the list after everything has
succeeded.
