memcg: fix mutex not unlocked on memcg_create_kmem_cache fail path
Commit 842e2873697e ("memcg: get rid of kmem_cache_dup()") introduced a
mutex for memcg_create_kmem_cache() to protect the tmp_name buffer that
holds the memcg name. It failed to unlock the mutex if this buffer
could not be allocated.
This patch fixes the issue by appropriately unlocking the mutex if the
allocation fails.
