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.
