audiohal: Add diagnostics to investigate HAL call crashes

This is intended to clarify whether surprising zeroing out of HAL
control structures happens to a particular HAL module, or to any
HAL module at random.

Unfortunately, the crash itself can't be prevented as
audioflinger can't work around a HAL outage, and needs to be
restarted anyway.
