salvager: Fix in-memory invalid linktable counts

When we have a nonexistant or invalid linktable, we manually set all
of the linkcounts to 1, since we're recreating the link table from
scratch. However, we also have a linkCount count in our in-memory
allInodes array, which could be populated by garbage if we had a
garbage linktable. So make sure to set our in-memory linkCount to 1
for each inode, so we don't use garbage linkcount data.
