[PATCH Dovetail-v5.10.y] tick: irq_pipeline: fix regression in clockevents_exchange_devices()

[Philippe Gerum via Xenomai]

From: Philippe Gerum <r...@xenomai.org>

The recent change regarding the tick proxy device [1] introduced a
regression in clockevents_exchange_devices(), causing a corruption of
the device release list.

This does not affect the logic of the previous fix which remains
correct though.
