mm, hmm: use devm semantics for hmm_devmem_{add, remove}
commit 58ef15b765af0d2cbe6799ec564f1dc485010ab8 upstream.
devm semantics arrange for resources to be torn down when
device-driver-probe fails or when device-driver-release completes.
Similar to devm_memremap_pages() there is no need to support an explicit
remove operation when the users properly adhere to devm semantics.
Note that devm_kzalloc() automatically handles allocating node-local
memory.
