net: Prevent use after free in netif_napi_set_irq_locked()
The cpu_rmap_put() will call kfree() when the last reference is dropped
so it could result in a use after free when we dereference the same
pointer the next line. Move the cpu_rmap_put() after the dereference.
Fixes: bd7c00605ee0 ("net: move aRFS rmap management and CPU affinity to core")
