audio hal: temporary fix for speaker device ref counting issue

Fix for issue b/62337071 (commit 322047ed) caused a problem with
device enable ref counting likely causing b/65363602.
As the problematic code does not affect walleye (no speaker protection)
we remove it until a better solution is found for devices with stereo
speaker and speaker protection feature.

Bug: 65363602
Test: verify repro steps in b/65363602
