KVM: x86/mmu: Passing up the error state of mmu_alloc_shadow_roots()
Just like on the optional mmu_alloc_direct_roots() path, once shadow
path reaches "r = -EIO" somewhere, the caller needs to know the actual
state in order to enter error handling and avoid something worse.
Fixes: 4a38162ee9f1 ("KVM: MMU: load PDPTRs outside mmu_lock")
