Revert "ipc4: relax the IPC timeout checks and be nicer to other threads"

When a stream is triggered to start, host kernel first sendis trigger
start ipc message to fw and then start host dma for this stream.
Ipc_wait_for_compound_msg is used to wait for all pipelines in the
stream to be complete and need to be done fast since it blocks host
to start hda dma. The reverted commit adds a 10 ms delay and results
to host copier xrun warning for it can't get data from host dma. And
this commit also makes a negative effect for stream_start_offset
calculation, so revert it.

This reverts commit 909a327.
