Robert Schmidt 6ef8dadd88 Only add SRS TDA if SRS is activated 
Since the parent commit, the TDA for UL scheduling is dynamically
selected, instead of being hardcoded to specific indices. We can thus
also omit the SRS TDA if no SRS is configured.

Also add SRS-specific TDAs if we schedule further into the future.
