x86: don't override INVALID_M2P_ENTRY with SHARED_M2P_ENTRY

While in most cases code ahead of the invocation of set_gpfn_from_mfn()
deals with shared pages, at least in set_typed_p2m_entry() I can't spot
such handling (it's entirely possible there's code missing there). Let's
try to play safe and add an extra check.
