tests: shell: bogus EBUSY errors in transactions
Make sure reference tracking during transaction update is correct by
checking for bogus EBUSY error. For example, when deleting map with
chain reference X, followed by a delete chain X command.
This test is covering the following paths:
- prepare + abort (via -c/--check option)
- prepare + commit
- release (when netns is destroyed)
