ipc: propagate unbind event in all cases

Unbind used to be ignored for components in the same pipeline
But there are some code that depends on the event and
need to have it in all situations, i.e. dai_zephyr_unbind
or cross-core DP connections in the same pipeline

Propagate the event in all cases
