hdparm-9.32: major bug fixes

hdparm-9.32 is now released. This includes fixes for the bugs introduced in 9.27 (which nobody emailed me about). So now, many flags such as -B and -M should be working again for most people.

Note: due to a bug in libata/libahci in recent kernels, some commands may still appear to fail. This is NOT an hdparm bug. A kernel fix is required (not yet available).
