[PATCH 3/3] media: ivtv: Fix potential double free on ALSA initialization failure

[Guangshuo Li]

After snd_ivtv_card_create() succeeds, the card's private_free callback
owns itvsc. snd_card_free() already invokes that callback on subsequent
initialization failures, so the explicit kfree() frees itvsc twice.

Remove the redundant free.

This issue was found by our static analysis tool under development.
