UBIFS: do not read flash unnecessarily
This fix makes the 'dbg_check_old_index()' function return immediately if debugging is disabled, instead of executing incorrect 'goto out' which causes UBIFS to: 1. Allocate memory 2. Read the flash On every commit. OK, we do not commit that often, but it is still silly to do unneeded I/O anyway. Credits to coverity for spotting this silly issue.
