ASoC: dapm: Fix uninitialized variable in snd_soc_dapm_get_enum_double()

If soc_dapm_read() fails, reg_val will be uninitialized, and bogus
values will be written later:

sound/soc/soc-dapm.c: In function 'snd_soc_dapm_get_enum_double':
sound/soc/soc-dapm.c:2862:15: warning: 'reg_val' may be used uninitialized in this function [-Wmaybe-uninitialized]
  unsigned int reg_val, val;
               ^

Return early on error to fix this.

Introduced by commit ce0fc93ae56e2ba50ff8c220d69e4e860e889320 ("ASoC:
Add DAPM support at the component level").
