too many 'd's

I'm not convinced this works.  In iio_str_to_fixpoint if fract_mult ==1
and the value passed is say 1.2 we will get 1 + fract_mult*2 = 3.

Maybe it's just too early in the morning!  fract_mult = 0 would probably
do the job, but this does all seem rather silly given we can just use
the kstrto* function in the integer case rather than bludgeoning it
into the fixed point string reader.
