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.

replace functions which are only available in glib-2.24
...
Currently the minimal supported version of glib is 2.22.
Since testing is done with a glib that claims to be 2.22, but in fact
has APIs from newer version of glib, this bug was not caught during
submit of the patch referenced below.
Replace g_realloc_n, which is available only since 2.24, with g_renew.
