genirq: Fix missing return value in irq_destroy_ipi()

Commit 7cec18a3906b changed the return type of irq_destroy_ipi to int, but
missed adding a value to one return statement. Fix this to silence the
resulting compiler warning:

kernel/irq/ipi.c In function ‘irq_destroy_ipi’:
kernel/irq/ipi.c:128:3: warning: ‘return’ with no value, in function returning non-void [-Wreturn-type]

Fixes: 7cec18a3906b "genirq: Add error code reporting to irq_{reserve,destroy}_ipi"
