    xen/lzo: Remove more remanants of TMEM
    
    This logic was inserted by commit 447f613c5404 ("lzo: update LZO compression
    to current upstream version") but was only relevant for the TMEM logic, so
    should have been deleted in commit c492e19fdd05 ("xen: remove tmem from
    hypervisor")
    
    Fixes: c492e19fdd05 ("xen: remove tmem from hypervisor")
