ALSA: hda: intel: Don't free card in the probe work
If the delayed probe fails, azx_probe_work() frees the card and clears
the drvdata. azx_remove() reads the card before it waits for the probe
work with cancel_delayed_work_sync() so when the device is removed while
the probe work is running, it frees the card again after the work has
already freed it.
Only disconnect the card in the work so that its slot is released right
away and leave freeing it to azx_remove().
