irqdomain: Fix up const problem in irq_domain_set_name()

In irq_domain_set_name() a const pointer is passed in, and then the
const is "lost" when container_of() is called.  Fix this up by properly
preserving the const pointer attribute when container_of() is used to
enforce the fact that this pointer should not have anything at it
changed.
