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.
