hal: Fix the input device is disabled when VOICE and VOIP are active

Tx mute is observed when VOICE and VOIP are active.When voice and voip
usecases are present, which share the same backend, then the Tx device
disable/enable sequence isn't properly follwed, which cause  disabling
tx mic.

Fix this by adding proper check at disable/enable of devices
for capture usecases that share same backend.
