KVM: x86: Remove guest mode check from kvm_check_nested_events

Browse Source 
A survey of the callsites reveals that they all ensure the vCPU is in
guest mode before calling kvm_check_nested_events. Remove this dead
code so that the only negative value this function returns (at the
moment) is -EBUSY.
