ENGR00295423-3 ASoC: fsl_ssi: Don't disable SSIEN if SSI is already enabled

If disabling SSI when SSI is already in the working state, the whole running
substream would be broken. Thus we here replace it to a safer way -- saving
the current SSIEN value and restore it afterward.

This patch also adds a slot number checking code before setting slot number.
