[PATCH 1/3] Remove unnecessary duplicate check.

[Günther Noack]

Hello developers,

this and the following two patches are some trivial bugs found with
the Clang static analyzer.  Patch 1 and 2 remove unnecessary duplicate
checks, patch 3 addresses a copy&paste glitch which mixes up int and
unsigned int.

Thanks,
Guenther
