Fix duplicate bogus share field when link sharing is not allowed

Whenever link share is not allowed, it was outputting a bogus sharing
field which name would conflict with the regular sharing field.

This fix makes sure that the bogus sharing field with "Resharing not
allowed" message only appears when triggered by removed share
permissions.
