genirq: GENERIC_IRQ_IPI depends on SMP
[ Upstream commit 0f5209fee90b4544c58b4278d944425292789967 ]
The generic IPI code depends on the IRQ affinity mask being allocated
and initialized. This will not be the case if SMP is disabled. Fix up
the remaining driver that selected GENERIC_IRQ_IPI in a non-SMP config.
