ASoC: max98090: fix deadlock in max98090_dapm_put_enum_double()
Commit 62d5ae4cafb7 ("ASoC: max98090: save and restore SHDN when
changing sensitive registers SHDN bit") uses dapm_mutex to protect SHDN
bit. However, snd_soc_dapm_put_enum_double() in
max98090_dapm_put_enum_double() acquires the dapm_mutex again which
cause a deadlock.
Use snd_soc_dapm_put_enum_double_locked() instead to fix the deadlock.
