x86/mem_sharing: Fix build with !CONFIG_XSM

A build fails with:

  mem_sharing.c: In function ‘copy_special_pages’:
  mem_sharing.c:1649:9: error: ‘HVM_PARAM_STORE_PFN’ undeclared (first use in this function)
           HVM_PARAM_STORE_PFN,
           ^~~~~~~~~~~~~~~~~~~
  ...

This is because xsm/xsm.h includes xsm/dummy.h for the !CONFIG_XSM case, which
brings public/hvm/params.h in.
