Subject: s390x/pci: Always delete and free the release_timer

Include-If: %if 0%{?suse_version} == 1315
Git-commit: d648a3e62d5e726526f9df283341999792f4fbf9
References: bsc#1179725

We should always get rid of it. I don't see a reason to keep the timer
alive if the devices are going away. This looks like a memory leak.

(hmp) device_add virtio-mouse-pci,id=test
(hmp) device_del test
-> guest notified, timer pending.
-> guest does not react for some reason (e.g. crash)
-> s390_pcihost_timer_cb(). Timer not pending anymore. qmp_unplug().

-> Device deleted. Timer expired (not pending) but not freed.
