[PATCH] KVM: MTRR: Use default type for non-MTRR-covered gfn before WARN_ON

[Alex Williamson]

The patch was munged on commit to re-order these tests resulting in
excessive warnings when trying to do device assignment.  Return to
original ordering: https://lkml.org/lkml/2015/7/15/769

Fixes: 3e5d2fdceda1 ("KVM: MTRR: simplify kvm_mtrr_get_guest_memory_type")
