KVM: x86: Swap the dst and src operand for MOVNTDQA

KVM: x86: Swap the dst and src operand for MOVNTDQA

Swap the MOVNTDQA operands, as MOVNTDQA does NOT in fact have "the same
characteristics as 0F E7 (MOVNTDQ)"; MOVNTDQA loads from memory and stores
to registers, while MOVNTDQ loads from registers and stores to memory.

Per the SDM:

 MOVNTDQ - Move packed integer values in xmm1 to m128 using non-temporal
           hint.

 MOVNTDQA - Move double quadword from m128 to xmm1 using non-temporal hint
            if WC memory type.
