[Qemu-devel] [PULL 02/38] s390x/pci: return directly if create zpci failed

[Cornelia Huck <cornelia.huck@de.ibm.com>]

From: Yi Min Zhao <zyimin@linux.vnet.ibm.com>

In the case that zpci is automatically created, we did not return
immediately on failure, which would lead to NULL pointer dereferencing.
Let's fix it.
