Subject: [PATCH 1/3] target: remove iscsit_find_cmd_from_itt_or_dump()

Code is a copy of iscsit_find_cmd_from_itt().  Afaics this is debug code
from at least two years ago.  Either the bug in question has been long
fixed or this debug code doesn't help fixing it.  Whichever way you look
at it, we should remove the debug code.
