sched/dl/Documentation: Correct the definition of density as C_i/min{D_i,P_i}
C_i/min{D_i,T_i}, where T_i is not referred before, should be
substituted with C_i/min{D_i,P_i}.

If D_i != P_i for some task, then it is possible to define the density of
- a task as C_i/min{D_i,T_i}, and EDF is able to respect all the deadlines

densities of the tasks running on such a CPU is smaller or equal than 1
(notice that this condition is only sufficient, and not necessary).
