dll: FspFsctlServiceVersion

Browse Source 
During file system volume creation FspFsctlCreateVolume calls FspFsctlServiceVersion
which examines the version of the driver in use and initializes the variables
FspFsctlTransactCode and FspFsctlTransactBatchCode with either the new
FSP_IOCTL_TRANSACT* codes or the old FSP_FSCTL_TRANSACT* codes.
