[U-Boot] [PATCH] ubifs: don't self assign values

[Jeroen Hofstee]

It seems the code tries to trick the compiler the argument
is actually used. However compilers became too smart too
fool them so easily an now warn. Checking gcc and clang
does not seem to emit a warning. If so it should be decorated
with unused / (void).
