MIPS: KVM: Combine entry trace events into class
Combine the kvm_enter, kvm_reenter and kvm_out trace events into a
single kvm_transition event class to reduce duplication and bloat.
Suggested-by: Steven Rostedt <rostedt@goodmis.org>
Fixes: 93258604ab6d ("MIPS: KVM: Add guest mode switch trace events")
