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.
