ASoC: amd: acp: Fix initialization of ext_intr_stat1 in i2s_irq_handler()

Clang warns:

  ../sound/soc/amd/acp/acp-platform.c:117:19: error: variable 'ext_intr_stat1' is uninitialized when used here [-Werror,-Wuninitialized]
                          if (stream && (ext_intr_stat1 & stream->irq_bit)) {
                                         ^~~~~~~~~~~~~~
  ../sound/soc/amd/acp/acp-platform.c:97:35: note: initialize the variable 'ext_intr_stat1' to silence this warning
          u32 ext_intr_stat, ext_intr_stat1, i;
                                           ^
                                            = 0
  1 error generated.

The variable was not properly renamed, correct it to resolve the
warning.
