mm: shrinker: rename {prealloc|unregister}_memcg_shrinker() to shrinker_memcg_{alloc|remove}()

Browse Source 
With the new shrinker APIs, there is no action such as prealloc, so rename
{prealloc|unregister}_memcg_shrinker() to shrinker_memcg_{alloc|remove}(),
which corresponds to the idr_{alloc|remove}() inside the function.
