storage_util: Remove unnecessary check
storage_util: Remove unnecessary check

Commit id 'a48c71411' altered the logic a bit and didn't
remove an unnecessary check as info.encryption is true when
vol->target.encryption != NULL, so if we enter the if segment
with info.format == VIR_STORAGE_FILE_RAW && vol->target.encryption
!= NULL, then there's no way info.encryption could be false.
