[PATCH v2] ASoC: amd: yc: Fix the wrong return value

[Venkata Prasad Potturu <venkataprasad.potturu@xxxxxxx>]

With the current implementation, when ACP driver fails to read
ACPI _WOV entry then the DMI overrides code won't invoke,
may cause regressions for some BIOS versions.

Add a condition check to jump to check the DMI entries incase of
ACP driver fail to read ACPI _WOV method.

Fixes: 4095cf872084 (ASoC: amd: yc: Fix for enabling DMIC on acp6x via _DSD entry)

Changes since v1:
	- removed redundant "&& wov_en" check
