kdb: Remove unused KDB_FLAG_ONLY_DO_DUMP
This code cleanup was missed in the original kdb merge, and this code is simply not used at all. The code that was previously used to set the KDB_FLAG_ONLY_DO_DUMP was removed prior to the initial kdb merge. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
