Sean Christopherson 4f4c4a3ee5 KVM: x86: Trace all APICv inhibit changes and capture overall status

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.
