[PATCH 04/11] pack-bitmap: drop filter in prepare_bitmap_walk()

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <derrickstolee@github.com>

Now that all consumers of prepare_bitmap_walk() have populated the
'filter' member of 'struct rev_info', we can drop that extra parameter
from the method and access it directly from the 'struct rev_info'.
