ASoC: cs35l41: Initialize completion object before requesting IRQ

[ Upstream commit 5ad668a9ce83d819701fb7abc1c2236049ec15c2 ]

Technically, an interrupt handler can be called before probe() finishes
its execution, hence ensure the pll_lock completion object is always
initialized before being accessed in cs35l41_irq().
