ASoC: intel/sdw_utils: Assign initial value in asoc_sdw_rt_amp_spk_rtd_init()

Browse Source 
[ Upstream commit 5fb3878216aece471af030b33a9fbef3babd8617 ]

Initialize "ret" with "-EINVAL" to handle cases where "strstr()" for
"codec_dai->component->name_prefix" doesn't find "-1" nor "-2". In that
case "name_prefix" is invalid because for current implementation it's
expected to have either "-1" or "-2" in it. (Maybe "-3", "-4" and so on
in the future.)
