Merge branch 'tb/fsck-no-progress'

"git fsck --no-progress" still spewed noise from the commit-graph
subsystem, which has been corrected.

* tb/fsck-no-progress:
  commit-graph.c: avoid duplicated progress output during `verify`
  commit-graph.c: pass progress to `verify_one_commit_graph()`
  commit-graph.c: iteratively verify commit-graph chains
  commit-graph.c: extract `verify_one_commit_graph()`
  fsck: suppress MIDX output with `--no-progress`
  fsck: suppress commit-graph output with `--no-progress`
