ASOC: SOF: Intel: hda-loader: do not wait for HDaudio IOC

Commit 9ee3f0d (" ASOC: SOF: Intel: hda-loader: only wait for
HDaudio IOC for IPC4 devices") removed DMA wait for IPC3 case.
Proceed and remove the wait for IPC4 devices as well.

There is no dependency to IPC version in the load logic and
checking the firmware status is a sufficient check in case of
errors.

The removed code also had a bug in that -ETIMEDOUT is returned
without stopping the DMA transfer.
