KVM: x86: Don't inject PV async #PF if SEND_ALWAYS=0 and guest state is protected
Don't inject PV async #PFs into guests with protected register state, i.e.
SEV-ES and SEV-SNP guests, unless the guest has opted-in to receiving #PFs
at CPL0. For protected guests, the actual CPL of the guest is unknown.
Note, no sane CoCo guest should enable PV async #PF, but the current state
of Linux-as-a-CoCo-guest isn't entirely sane.
