em28xx-dvb, em28xx-alsa and em28xx-ir are typically initialized
asyncrhronously. The exception for it is when those modules
are loaded before em28xx (or before an em28xx card insertion) or
when they're built in.
Make the extentions to always load asynchronously. That allows
having all DVB firmwares loaded synchronously with udev-182.
