[PATCH AUTOSEL 5.7 013/388] ASoC: fsl_esai: Disable exception interrupt before scheduling tasklet

[Sasha Levin]

From: Shengjiu Wang <shengjiu.wang at nxp.com>

[ Upstream commit 1fecbb71fe0e46b886f84e3b6decca6643c3af6d ]

Disable exception interrupt before scheduling tasklet, otherwise if
the tasklet isn't handled immediately, there will be endless xrun
interrupt.

Fixes: 7ccafa2b3879 ("ASoC: fsl_esai: recover the channel swap after xrun")
