x86/shadow: correct GFN use by sh_unshadow_for_p2m_change()

Luckily sh_remove_all_mappings()'s use of the parameter is limited to
generation of log messages. Nevertheless we'd better pass correct GFNs
around:
- the incoming GFN, when replacing a large page, may not be large page
  aligned,
- incrementing by page-size-scaled values can't be right.
