misc: mods: fix offset for large allocations

Browse Source 
Fix MODS_VIRTUAL_TO_PHYSICAL for allocations exceeding 4GB

It's unlikely for us to support such large allocations,
but if we ever did, integer overflow would truncate the
allocation offset, resulting in the incorrect PA being
returned.

This change also brings the driver up to date with
the Perforce copy and fixes the version.
