[PATCH 2/2] kconfig: add unexpected data itself to warning

[Paul Bolle <pebolle@tiscali.nl>]

If the .config parser runs into unexpected data it emits a warnings like
    .config:6911:warning: unexpected data

Add the unexpected data itself to the warning too, to make it easier to
discover what is going wrong:
     .config:6911:warning: unexpected data: CONFOG_CHARGER_TPS65217=m
