NR UE: add assert for reserved bits per symbol not multiple of Qm

map_overlapped_ack() divides num_reserved_bits_on_sym by Qm to get the
number of reserved REs. Add assertion to catch cases where the reserved
bit count is not a multiple of Qm, which would indicate a bug in the
upstream UCI-on-PUSCH mapping.
