uic: Avoid use of Q_UNUSED in the generated code

Browse Source 
Instead, use (void)x; directly.

The current use of Q_UNUSED(x); generates warnings for an
empty statement the expansion of Q_UNUSED contains a semicolon
already.

Emitting Q_UNUSED(x) without the extra semicolon would be
an option, too, but as the future of Q_UNUSED's embedded
semicolon seems unclear right now, avoid its use altogether.

The change affects only generated code that's barely ever
read by a human, so the overall utility of "improved readability"
of Q_UNUSED in that place is questionable anyway.
