[PATCH v2 1/2] 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. Only when cascade failed, roots_bitmap is
freed otherwise it leaks. Since cascade_pseudo_merges_1() only use
roots_bitmap as a mutable reference not takes roots_bitmap's ownership
we'd better remove `if(cascade_pseudo_merges_1)` and frees roots_bitmap
anyway.
