Ben Hutchings d4925800a4 lib: cpu_rmap: Fix potential use-after-free in irq_cpu_rmap_release() 
[ Upstream commit 7c5d4801ec ]

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: 4e0473f106 ("lib: cpu_rmap: Avoid use after free on rmap->obj array entries")
