ASoC: acpi: fix: continue searching when machine is ignored

Browse Source 
[ Upstream commit a3e620f8422832afd832ad5e20aa97d0c72bada8 ]

The machine_quirk may return NULL which means the acpi entries should be
skipped and search for next matched entry is needed, here add return
check here and continue for NULL case.
