sched/topology: Drop memset() from init_rootdomain()

There are only two callers of init_rootdomain(). One of them passes a
global to it and another one sends dynamically allocated root-domain.

There is no need to memset the root-domain in the first case as the
structure is already reset.

Update alloc_rootdomain() to allocate the memory with kzalloc() and
remove the memset() call from init_rootdomain().
