KVM: x86/mmu: Drop 'shared' param from tdp_mmu_link_page()

Browse source

Drop @shared from tdp_mmu_link_page() and hardcode it to work for
mmu_lock being held for read.  The helper has exactly one caller and
in all likelihood will only ever have exactly one caller.  Even if KVM
adds a path to install translations without an initiating page fault,
odds are very, very good that the path will just be a wrapper to the
"page fault" handler (both SNP and TDX RFCs propose patches to do
exactly that).

No functional change intended.
