[libromdata] ISOPrivate::host32(): Fix a typo that broke "Volume Size" on CD-i volumes.

Need to use be32_to_cpu() for 32-bit values, not be16_to_cpu().

This fixes a regression from commit 5cfce44312.
([libromdata] ISO: Always use host-endian except for CD-i, in which case, always use big-endian.)

Affects: v1.8 - v2.5

NOTE: v1.8 was the first version with CD-i support, so this was
effectively "always" broken.
