lib: cpu_rmap: Fix potential use-after-free in irq_cpu_rmap_release()
irq_cpu_rmap_release() calls cpu_rmap_put(), which may free the rmap.
So we need to clear the pointer to our glue structure in rmap before
doing that, not after.
Fixes: 4e0473f1060a ("lib: cpu_rmap: Avoid use after free on rmap->obj array entries")
