KVM: PPC: Fix refactoring goof in kvmppc_e500mc_init()

Fix a build error due to a mixup during a recent refactoring.  The error
was reported during code review, but the fixed up patch didn't make it
into the final commit.

Fixes: 474856bad921 ("KVM: PPC: Move processor compatibility check to module init")
