[PATCH 3.8 018/166] USB: spcp8x5: correct handling of CS5 setting

From: Colin Leitner <colin.leitner@googlemail.com>

commit 711fbdfbf2bc4827214a650afe3f64767a1aba16 upstream.

This patch removes an erroneous check of CSIZE, which made it impossible to set
CS5.

Compiles clean, but couldn't test against hardware.
