MIPS: OCTEON: irq: Fix octeon_irq_force_ciu_mapping()
For irq_domain_associate() to work the virq descriptor has to be
pre-allocated in advance. Otherwise the following happens:
WARNING: CPU: 0 PID: 0 at .../kernel/irq/irqdomain.c:527 irq_domain_associate+0x298/0x2e8
error: virq128 is not allocated
Modules linked in:

Use irq_alloc_desc_at() to avoid the above problem.
