Add a command to know the calculated value for ZHPF buffer when ZHPFOPTS has SYSTEM parameter

For ZHPFOPTS  if SYSTEM is specified, the maximum data transfer size for zHPF I/O requests is determined by the system based on the maximum data transfer size supported by the device and its online CHPIDs.

So if something changed on CHPID, Switch , DS8K, the buffer size of ZHPF change. In this case it will be a good to put the buffer size value on an SMF record and to have a command to display the buffer size value.
