dmg: prevent out-of-bounds array access on terminator
When a terminator is reached the base for offsets and sectors is stored.
The following records that are processed will use this base value.
If the first record we encounter is a terminator, then calculating the
base values would result in out-of-bounds array accesses. Don't do
that.
