vfio/mdev: Fix missing static's on MDEV_TYPE_ATTR's

These should always be prefixed with static, otherwise compilation
will fail on non-modular builds with

ld: samples/vfio-mdev/mbochs.o:(.data+0x2e0): multiple definition of `mdev_type_attr_name'; samples/vfio-mdev/mdpy.o:(.data+0x240): first defined here

Fixes: a5e6e650 ("sample: vfio bochs vbe display (host device for bochs-drm)")
Fixes: d61fc96f ("sample: vfio mdev display - host device")
