mm: shmem: assign a lock class to the unused huge shrinklist
The unused huge shrinklist shares the default list_lru lock class with the
dentry LRU. Although they use distinct lock instances, lockdep conflates
their dependencies and reports a circular locking dependency:
WARNING: possible circular locking dependency detected
Give the unused huge shrinklist a dedicated lock class to fix this
false-positive lockdep warning.
