ASoC: cs42l43: Initialize ret in default case in cs42l43_pll_ev()

clang warns (or errors with CONFIG_WERROR=y):

  sound/soc/codecs/cs42l43.c:1371:2: error: variable 'ret' is used uninitialized whenever switch default is taken [-Werror,-Wsometimes-uninitialized]
   1371 |         default:
        |         ^~~~~~~
  sound/soc/codecs/cs42l43.c:1377:9: note: uninitialized use occurs here
   1377 |         return ret;
        |                ^~~
  sound/soc/codecs/cs42l43.c:1349:9: note: initialize the variable 'ret' to silence this warning
   1349 |         int ret;
        |                ^
        |                 = 0
  1 error generated.

Initialize ret to 0 in the default case, as there was nothing to do for
other event types.
