[PATCH] sched/deadline: remove unused dl_bandwidth

From: Miaohe Lin
Date: Tue May 23 2023 - 22:33:58 EST


The default deadline bandwidth control structure has been removed since
commit eb77cf1c151c ("sched/deadline: Remove unused def_dl_bandwidth")
leading to unused init_dl_bandwidth() and struct dl_bandwidth. Remove
them to clean up the code.
