Mikhail Zaslonko 30dc1a5ddd zdump/dfi_vmdump: Consider vmdump requested memory ranges ...

At the moment the memory range of processed vmdump always corresponds to
the highest defined byte (q v storage) obtained from Address Space
Information Block ignoring memory ranges specified in CP vmdump command.
This might lead to the invalid dump size calculation upon conversion to
s390 format.
Use Requested Range Table from ASIZBK to identify actual memory ranges
being dumped. Consider the end of the highest memory range as a vmdump
upper limit (dump memory size). In case no range table entries present
fall back to the original method using 'storage_size_def_store' value.
