s390/pci: Add missing virt_to_phys() for directed DIBV

Browse Source 
[ Upstream commit 4181b51c38 ]

In commit 4e4dc65ab5 ("s390/pci: use phys_to_virt() for AIBVs/DIBVs")
the setting of dibv_addr was missed when adding virt_to_phys(). This
only affects systems with directed interrupt delivery enabled which are
not generally available.
