[PATCH v2 0/3] pack-bitmap: fix memory leak if load_bitmap_entries_v1 failed

In pack-bitmap.c:load_bitmap_entries_v1, the function read_bitmap_1 allocates a bitmap and reads index data into it. However, if any of the validation checks following the allocation fail, the allocated bitmap is not freed, resulting in a memory leak. To avoid this, the validation checks should be performed before the bitmap is allocated.
