KVM: nVMX: Drop obsolete (and pointless) pdptrs_changed() check
Remove the pdptrs_changed() check when loading L2's CR3. The set of
available registers is always reset when switching VMCSes (see commit
e5d03de5937e, "KVM: nVMX: Reset register cache (available and dirty
masks) on VMCS switch"), thus the "are PDPTRs available" check will
always fail. And even if it didn't fail, reading guest memory to check
the PDPTRs is just as expensive as reading guest memory to load 'em.
