CVE-2025-39769

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix lockdep warning during rmmod

The commit under the Fixes tag added a netdevassertlocked() in bnxtfreentpfltrs(). The lock should be held during normal run-time but the assert will be triggered (see below) during bnxtremoveone() which should not need the lock. The netdev is already unregistered by then. Fix it by calling netdevassertlockedor_invisible() which will not assert if the netdev is unregistered.
