nanddump: update help message for BB method changes
--noskipbad will soon be replaced by --bb=dumpbad, and --omitbad is being removed entirely in favor of --bb=skipbad. This patch adds warnings when using inappropriate configurations and adds info to the help message. Please plan to migrate to the new usages shortly.
