Oops, sorry. I've grepped for 'alloc_p*' and didn't notice KVM was using
release_p*. I've checked for binary code changes with all paravirt guest

This fixes the following compiler warnings, that were introduced by me
on commit fa24f8e67c189b8b904c8a34f12e6dae9c14dbba.

arch/x86/kernel/kvm.c: In function 'paravirt_ops_setup':
arch/x86/kernel/kvm.c:233: warning: assignment from incompatible pointer type
arch/x86/kernel/kvm.c:234: warning: assignment from incompatible pointer type
arch/x86/kernel/kvm.c:235: warning: assignment from incompatible pointer type
