Colin Ian King 71411bd79e media: cx23885: Fix snd_card_free call on null card pointer
[ Upstream commit 7266dda2f1dfe151b12ef0c14eb4d4e622fb211c ]

Currently a call to snd_card_new that fails will set card with a NULL
pointer, this causes a null pointer dereference on the error cleanup
path when card it passed to snd_card_free. Fix this by adding a new
error exit path that does not call snd_card_free and exiting via this
new path.

Addresses-Coverity: ("Explicit null dereference")

Fixes: 9e44d63246a9 ("[media] cx23885: Add ALSA support")
