libsuspend: move to exponential backoff If for some reason the system can't suspend (usually a driver bug), libsuspend will currently attempt to retry suspend after 100ms. Because entering suspend takes a significant amount of CPU time, this can be extremely expensive and be a major contributor to rapid battery drain. Move autosuspend to use exponential backoff if the previous suspend attempt failed. bug 32092914 Change-Id: I3e9e944f290de5f1853a02e3f61721ba9159df46
