ASoC: xtfpga-i2s: Add missing __rcu annotation
tx_substeam is accessed using the RCU API and hence should have the __rcu
annotation. Fixes the following sparse warnings:
sound/soc/xtensa/xtfpga-i2s.c:165:24: error: incompatible types in
comparison expression (different address spaces)
sound/soc/xtensa/xtfpga-i2s.c:165:24: error: 'struct snd_pcm_substream
[noderef] <asn:4>*' versus
