ASoC: codecs: wsa-macro: fix uninitialized stack variables with name …

…prefix Driver compares widget name in wsa_macro_spk_boost_event() widget event callback, however it does not handle component's name prefix. This leads to using uninitialized stack variables as registers and register values. Handle gracefully such case.
