[PATCH 51/66] ALSA: vx222: Fix assignment in if condition

[Takashi Iwai <tiwai@xxxxxxx>]

PCI VX222 driver code contains lots of assignments in if condition,
which is a bad coding style that may confuse readers and occasionally
lead to bugs.

This patch is merely for coding-style fixes, no functional changes.
