Fix a small bug with total_res in gNB PUSCH symbol processing

Replaced total_res with res_per_task when deciding whether to start a threadpool
task or not. This does not have big impact on the software as the
nr_pusch_symbol_processing will recheck ul_valid_re_per_slot anyway but it may
reduce the number of thread pool tasks created.
