Make some structs and functions static to fix build warning, parts of
warning shown below,

amples/vfio-mdev/mtty.c:730:5: warning: symbol 'mtty_create' was not declared. Should it be static?
samples/vfio-mdev/mtty.c:780:5: warning: symbol 'mtty_remove' was not declared. Should it be static?
samples/vfio-mdev/mtty.c:802:5: warning: symbol 'mtty_reset' was not declared. Should it be static?
