ALSA: hda/cirrus: Correct the full scale volume set logic

[ Upstream commit 08b613b9 ]

This patch corrects the full-scale volume setting logic. On certain
platforms, the full-scale volume bit is required. The current logic
mistakenly sets this bit and incorrectly clears reserved bit 0, causing
the headphone output to be muted.
