ASoC: tegra: Fix MBDRC bypass mode check

MBDRC supports different modes of operation. There is no configuration
required for bypass mode. The hw_params() call does not filter bypass
mode correctly and it leads to following Smatch static checker warning:

  sound/soc/tegra/tegra210_mbdrc.c:778 tegra210_mbdrc_hw_params()
  warn: bitwise AND condition is false here

Fix this condition by using proper mode mask and just return for bypass
mode.
