Pauli Virtanen c89acd3e1c alsa: acp: fix volume rounding down causing mute 
Some ALSA devices have minimum HW volume value that is muted.  ALSA
indicates it with SND_CTL_TLV_DB_GAIN_MUTE = -9999999 dB/100 volume dB.
When rounding down to HW volume, we may get this muted value.

When determining splitting of volumes to mixers and soft volume, we
don't want HW mixers to set volume to muted, unless the target volume is
actually muted.

Fix by adding element_ask_unmuted_dB_vol() that rounds up if the asked
rounding mode resulted to mute.

This fixes mic getting muted at low volume despite ALSA reporting the dB
values correctly.

Fixes #4890
