Rakib Mullick 07a1c2d113 irq/core: Fix boot crash when the irqaffinity= boot parameter is passed on CPUMASK_OFFSTACK=y kernels(v1)
commit 10d94ff4d5 upstream.

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().
