Subject: [PATCH] kvm:powerpc:Fix incorrect return statement in the function mpic_set_default_irq_routing

From: Nicholas Krause <[email-masked]>
Date: Fri, 7 Aug 2015 11:54:53 -0400

This fixes the incorrect return statement in the function
mpic_set_default_irq_routing from always returning zero
to signal success to this function's caller to instead
return the return value of kvm_set_irq_routing as this
function can fail and we need to correctly signal the
caller of mpic_set_default_irq_routing when the call
to this particular function has failed.
