irqchip/mips-gic: Don't touch vl_map if a local interrupt is not routable
When a GIC local interrupt is not routable, it's vl_map will be used
to control some internal states for core (providing IPTI, IPPCI, IPFDC
input signal for core). Overriding it will interfere core's intetrupt
controller.
Do not touch vl_map if a local interrupt is not routable, we are not
going to remap it.
Before dd098a0e0319 (" irqchip/mips-gic: Get rid of the reliance on
irq_cpu_online()"), if a local interrupt is not routable, then it won't
be requested from GIC Local domain, and thus gic_all_vpes_irq_cpu_online
won't be called for that particular interrupt.
Fixes: dd098a0e0319 (" irqchip/mips-gic: Get rid of the reliance on irq_cpu_online()")
