[PATCH] target/ppc: Fix the order of kvm_enable judgment about kvmppc_set_interrupt()

[jianchunfu]

It's unnecessary for non-KVM accelerators(TCG, for example),
to call this function, so change the order of kvm_enable() judgment.

The static inline function that returns -1 directly does not work
 in TCG's situation.
