ALSA: vx222: fix null-ptr-deref
a recent refactor created a null pointer vx in snd_vx222_probe().
The vx pointer should have been populated in snd_vx222_create() as
suggested in earlier version, otherwise vx->core.ibl.size will throw an
error.

[ 1.316799] RIP: 0010:snd_vx222_probe+0x155/0x290 [snd_vx222]
