soundwire: intel: initialise quirk_mask before reading it
sdw_master_read_intel_prop() declares quirk_mask without an initialiser
and ignores the return value of fwnode_property_read_u32(). When a BIOS
does not describe "intel-quirk-mask" for a link, the property read leaves
the variable untouched and stack garbage decides whether
SDW_INTEL_QUIRK_MASK_BUS_DISABLE is honoured, so the link may be marked
hw_disabled at random.
Initialise it to 0, matching is_link_enabled() in
sound/hda/core/intel-sdw-acpi.c.
Found by code inspection, not observed at run time.
