The hw_params() overwrites i2s_net settings for special cases like mono-channel support, however, it doesn't update ssi->i2s_net as set_dai_fmt() does.
This patch removes the local i2s_net variable and directly updates ssi->i2s_net in the hw_params() so that the driver can simply look up the ssi->i2s_net instead of reading the register.
