ALSA: usb-audio: Fix dB level of Bose Revolve+ SoundLink
Bose Revolve+ SoundLink (0a57:40fa) advertises invalid dB level for the speaker volume. This patch provides the correction in the mixer map quirk table entry. Note that this requires the prerequisite change to add min_mute flag to the dB map table.
