debug_sprintf_event/exception are called even for debug events with a disabling debug level. All other functions already do the check in a wrapper function. Lets do the same here. Due to the var_args the compiler rejects to make this function inline. So let's wrap this via a macro. This patch saves around 80 ns on my z196 for a KVM round trip (we have two debug statements for entry and exit) when KVM is build as a module. The savings for built-in drivers is smaller as we then avoid the PLT overhead for a function call.
