ASoC: fsl_sai: initialize is_dsp_mode flag

[ Upstream commit a23924b7dd7b748fff8e305e1daf590fed2af21b ]

Initialize is_dsp_mode flag in the beginning of function
fsl_sai_set_dai_fmt_tr().

When the DAIFMT is DAIFMT_DSP_B the first time, is_dsp_mode is
true, then the second time DAIFMT is DAIFMT_I2S, is_dsp_mode
still true, which is a wrong state. So need to initialize
is_dsp_mode flag every time.
