Tong Zhang 8491f59e3b 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.

[    1.298398] BUG: kernel NULL pointer dereference, address: 00000000000001d8
[    1.316799] RIP: 0010:snd_vx222_probe+0x155/0x290 [snd_vx222]
