sched/deadline: No need to check p if dl_se is valid
Dan Carpenter reported new 'Smatch' warnings:

> kernel/sched/deadline.c:937 pick_next_task_dl() warn: variable dereferenced before check 'p' (see line 934)
BUG_ON() already fires if pick_next_dl_entity() doesn't return a valid
dl_se. No need to check if p is valid afterward.
