In the GETTEMP_GUESS case, dsk->db_entry is NULL, so this crashes. I
actually noticed this because "hddtemp -u F /dev/hda" was giving me
results in C not F, and I was trying to figure out why.
If the tool is guessing, the unit flag is ignored (see the code). I'm
not sure why this is done that way, but bug 365413 is kind of
relevant. Now that there is a -u flag, I'd think the conversion
should apply in the GUESS and KNOWN code paths.
Finally, the --unit/-u flag is not documented in the man page.
