audiohal: Remove timeouts in eventflag waits
Having a timeout is causing issues on hal driver thread startup.
If thread startup is delayed, then eventflag wait exits with
timeout. This leaves fmqs in an intermediate state, and a pending
wakeup for the server enables the client and the server to run
in parallel, causing races.
The legacy HAL interface didn't have any timeouts for read / write
operations, so there is no good reason for having them in
the wrapping interface.
The only difference with legacy HAL is that Treble HAL can be in
a separate process, and can crash, but this is handled separately.
Test: Check logs on startup, must be no fmq read / write errors
