[PATCH v10 5/7] bisect--helper: retire `--check-expected-revs` subcommand

[Miriam Rubio <mirucam@gmail.com>]

From: Pranit Bauva <pranit.bauva@gmail.com>

The `--check-expected-revs` subcommand is no longer used from the
git-bisect.sh shell script. Functions `check_expected_revs` and
`is_expected_revs` are also deleted.
