[PATCH 1/1] commit-reach: use unsigned int for flags in paint_down_to_common()

[Moumita <dhar61595@gmail.com>]

The `flags` variable in `paint_down_to_common()` stores bitwise flags
(PARENT1, PARENT2, and STALE), which are defined as `(1u << N)`.
Since these are already unsigned values,`flags` can also be declared as
`unsigned int` instead of `int`.
