[RFC,20/21] list: Format CHECK_DATA_CORRUPTION error messages consistently

Commit Message

Will Deacon March 24, 2020, 3:36 p.m. UTC

The error strings printed when list data corruption is detected are
formatted inconsistently.

Satisfy my inner-pedant by consistently using ':' to limit the message
from its prefix and drop the terminating full stops where they exist.
