Trace all APICv inhibit changes instead of just those that result in APICv being (un)inhibited, and log the current state. Debugging why APICv isn't working is frustrating as it's hard to see why APICv is still inhibited, and logging only the first inhibition means unnecessary onion peeling. Opportunistically drop the export of the tracepoint, it is not and should not be used by vendor code due to the need to serialize toggling via apicv_update_lock. Note, using the common flow means kvm_apicv_init() switched from atomic to non-atomic bitwise operations. The VM is unreachable at init, so non-atomic is perfectly ok.
