[PATCH] kvmppc: comply with requirement for kvm_arch_try_push_nmi

[ehrhardt@linux.vnet.ibm.com]

From: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com>

Since a recent patch all architetcures need a kvm_arch_try_push_nmi function.
Powerpc has no direct nmi equivalent, so this patch fixes only build for
powerpc by adding an empty stub.
If powerpc later wants to support the nmi monitor command somehow the function
can still be extended.
