6.12-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 4f0d91ba72811fd5dd577bcdccd7fed649aae62c ]
Print "entry->mac" before freeing "entry". The "entry" pointer is freed with kfree_rcu() so it's unlikely that we would trigger this in real life, but it's safer to re-order it.
