Julien Viet 909a3d942e KQueueEventLoop won't unregister active channels reusing a file descriptor (#9114)
Motivation:

The current KQueueEventLoop implementation does not process concurrent domain socket channel registration/unregistration in the order they actual
happen since unregistration are delated by an event loop task scheduling. When a domain socket is closed, it's file descriptor might be reused
quickly and therefore trigger a new channel registration using the same descriptor.

Consequently the KQueueEventLoop#add(AbstractKQueueChannel) method will overwrite the current inactive channels having the same descriptor
and the delayed KQueueEventLoop#remove(AbstractKQueueChannel) will remove the active channel that replaced the inactive one.

As active channels are registered, events for this file descriptor won't be processed anymore and the channels will never be closed.

Modifications:

Change the logic of KQueueEventLoop#remove(AbstractKQueueChannel) channels so it will check channels equality prior removal.

Result:

KQueueEventLoop won't remove anymore active channels reusing a file descriptor.
