[PATCH] sched: Remove unnecessary initialization in init_cfs_bandwidth() function

[Bitao Hu]

The root task group is statically defined, and non-root task groups
are allocated memory using kmem_cache_alloc() with the __GFP_ZERO
flag. In both cases, the corresponding 'struct cfs_bandwidth' is a
block of all-zero memory. Therefore, it is unnecessary to explicitly
set zeros in the init_cfs_bandwidth() function.
