powerpc: Return early if irq_host lookup type is wrong
If for some reason the code incrorectly calls the wrong function to
manage the revmap, not only should we warn, we should take action.
However, in the paths we expect to be taken every delivered interrupt
change to WARN_ON_ONCE. Use the if (WARN_ON(x)) format to get the
unlikely for free.
