File s390x-Don-t-do-a-normal-reset-on-the-ini.patch of Package qemu.22427

Subject: s390x: Don't do a normal reset on the initial cpu

References: bsc#1167075

The initiating cpu needs to be reset with an initial reset. While
doing a normal reset followed by a initial reset is not wrong per se,
the Ultravisor will only allow the correct reset to be performed.
