irq/core: Fix boot crash when the irqaffinity= boot parameter is passed on CPUMASK_OFFSTACK=y kernels(v1)
When the irqaffinity= kernel parameter is passed in a CPUMASK_OFFSTACK=y
kernel, it fails to boot, because zalloc_cpumask_var() cannot be used before
initializing the slab allocator to allocate a cpumask.
So, use alloc_bootmem_cpumask_var() instead.
Also do some cleanups while at it: in init_irq_default_affinity() remove
an #ifdef via using cpumask_available().
