USB: ffs-test: fix length argument of out function call
commit eb9c5836384cd2a276254df6254ed71117983626 upstream.
The out functions should only handle actual available data instead of the complete buffer.
Otherwise for example the ep0_consume function will report ghost events since it tries to decode
the complete buffer - which may contain partly invalid data.
