ALSA: vxpocket: Fix resource leak in vxpocket_probe error path

Browse Source 
When vxpocket_config() fails, vxpocket_probe() returns the error code
directly without freeing the sound card resources allocated by
snd_card_new(), which leads to a memory leak.

Add proper error handling to free the sound card and clear the
allocation bit when vxpocket_config() fails.
