ARM: KVM: fix ordering of 64bit coprocessor accesses
Commit 240e99cbd0
(ARM: KVM: Fix 64-bit coprocessor handling)
added an ordering dependency for the 64bit registers.
The order described is: CRn, CRm, Op1, Op2, 64bit-first.
Unfortunately, the implementation is: CRn, 64bit-first, CRm...
Move the 64bit test to be last in order to match the documentation.
