ASoC: SOF: Intel: use hdev->info.link_mask directly

The link_mask variable is not changed after setting to
hdev->info.link_mask until it is used for another purpose to get the
used SoundWire links and set to mach->mach_params.links. Besides, the
link_mask variable should be reset before any link id is added to the
link_mask. To fix the issue above and avoid confusing, use the
hdev->info.link_mask variable directly to check if the SoundWire link
is enabled.
