Quickfix for broken writes on FT2232H based programmers.

Not sure if this is the final/correct fix, but for now it definately
fixes writes on FT2232H hardware. I have tested this on both, the
DLP Design DLP-USB1232H, and the openbiosprog-spi hardware. 

Thanks to Joshua Roys <roysjosh@gmail.com> for the hint on IRC.
