[PATCH] pack-bitmap: remove checks before bitmap_free

["Lidong Yan via GitGitGadget" <gitgitgadget@gmail.com>]

From: Lidong Yan <502024330056@smail.nju.edu.cn>

In pack-bitmap.c:find_boundary_objects, we build a roots_bitmap and
cascade it to cb.base. However, I’m wondering why we only free
roots_bitmap when the cascade succeeds. It seems we could safely remove
this check and always free roots_bitmap afterward, which might provide
some performance benefits.

    In pack-bitmap.c:find_boundary_objects, remove cascade success check and
    always free roots_bitmap afterward to make static analysis tool works
    better.
