V4L/DVB: Video : pwc : Fix regression in pwc_set_shutter_speed caused by bad constant => sizeof conversion.
Regression was caused by my commit 6b35ca0d3d586b8ecb8396821af21186e20afaf0 which determined message size using sizeof rather than hardcoded constants. Unfortunately pwc_set_shutter_speed reuses a 2 byte buffer for a one byte message too so the sizeof was bogus in this case. All other uses of sizeof checked and are ok.
