Continue merge: Fix Spurious Hearing Aid Start and Stop Cmds
The original CL from AOSP
(chg-id:I33a175947b0118f0234ec6338c20ac6e7963a598) is not merged into
pi-dev-plus-asop due to some wrong Merged-In and Change-Id tags errors.
This CL is to continue the merge starting at pi-dev-plus-asop.
Prevent the spurious Start and Stop Commands that are send to the
Hearing Aids when there is audio suspend and resume, and also connection
and disconnections.
Also, make sure that the callback for the Audio Suspend and Resume are
done in the main thread; previously, it was running in the wrong socket
thread.
Lastly, make sure that the Connection Update callback are processed
correctly; previously, we are not checking that the right connection
interval are set and taking the callbacks done by service discovery.
