Lenovo H8: Always clear audio mute
The mute bit is set by ACPI before poweroff/going to suspend.
So clear it after resume, to have working volume control
even if the ACPI doesn't clear it on resume.
OSPM should control Audio mute with ec bit 0x30:6, so it is
safe to clear this bit even if the user has audio muted.
