vfio/ccw: calculate number of IDAWs regardless of format
The idal_nr_words() routine works well for 4K IDAWs, but lost its
ability to handle the old 2K formats with the removal of 31-bit
builds in commit 5a79859ae0f3 ("s390: remove 31 bit support").
Since there's nothing preventing a guest from generating this IDAW
format, let's re-introduce the math for them and use both when
calculating the number of IDAWs based on the bits specified in
the ORB.
