Markus Armbruster 93ef995b2c vfio-helpers: Fix qemu_vfio_open_pci() crash ...

qemu_vfio_open_common() initializes s->lock only after passing s to
qemu_vfio_dma_map() via qemu_vfio_init_ramblock().
qemu_vfio_dma_map() tries to lock the uninitialized lock and crashes.

Fix by initializing s->lock first.
