Subject: [PATCH AUTOSEL 4.4 13/92] ASoC: fsl_sai: Update is_slave_mode with correct value

From: Sasha Levin <[email-masked]>

[ Upstream commit ddb351145a967ee791a0fb0156852ec2fcb746ba ]

is_slave_mode defaults to false because sai structure
that contains it is kzalloc'ed.

Anyhow, if we decide to set the following configuration
SAI slave -> SAI master, is_slave_mode will remain set on true
although SAI being master it should be set to false.

Fix this by updating is_slave_mode for each call of
fsl_sai_set_dai_fmt.
