MLK-15039: ASoC: fsl_esai: Fix channels swap when recording 3 channels audio

The change introduced by commit 00c174b3b28a
("MLK-14525: ASoC: fsl_esai: channel swap issue in 3 channels or 5 channels")
is no longer valid after improvements added with commit c35bc6ae5c48
("MLK-14778: ASoC: fsl: imx-cs42888: Improve support for odd number of channels")

Because we use TDM instead of I2S for 3,5 and 7 channels we must
initialize ESAI with the actual number of channels. There is no need
to count the additional channel required when I2S was used.
