Description

With the change from a fixed size to a configurable packet alert queue (max), some issues with how the current queue is handled were exposed.

Improve that, to ensure there are no memory leaks with the dynamic allocation of the packet alerts queue.
--------------
This task will most likely be done as a backports-only candidate, in favour of the approach proposed by #5123 from 7.0.x onwards.

Will stop current work on this issue because we will try to follow the approach for #4943, and which could lead to a simpler/less convoluted way of handling the packet alert queue.
