Subject: s390x: fix build for --without-default-devices
MIME-Version: 1.0

Git-commit: 77280d33bc9cfdbfb5b5d462259d644f5aefe9b3
References: bsc#1179725

s390-pci-vfio.c calls into the vfio code, so we need it to be
built conditionally on vfio (which implies CONFIG_LINUX).

Fixes: cd7498d07fbb ("s390x/pci: Add routine to get the vfio dma available count")
