[Kir Kolyshkin]

A warning catched by clang:

> mount.c:869:71: error: variable 'progress' is uninitialized when used here
>       [-Werror,-Wuninitialized]
>   ...prev, MNT_WALK_NONE, fn, (struct list_head *) NULL, progress);
>                                                          ^~~~~~~~
> mount.c:802:4: note: expanded from macro 'MNT_TREE_WALK'
>                         _prgs++;
> \
>                         ^
> mount.c:867:14: note: initialize the variable 'progress' to silence this
> warning
>         int progress;
>                     ^
>                      = 0
