KVM: s390: pci: Fix NULL dereference on AIBV allocation failure

In the Linux kernel, the following vulnerability has been resolved:

KVM: s390: pci: Fix NULL dereference on AIBV allocation failure

The airq_iv_create() can return NULL on failure, but the return value was
never checked. If it fails, zdev->aibv will be NULL and fail when
dereferenced in kvm_zpci_set_airq(). Add a NULL check and free the
previously allocated AISB bit and zdev->aisb on failure.
