LU-12313 llite: Mark lustre_inode_cache as reclaimable

This is required for proper kernel memory available accounting.
Without it memory allocated to lustre_inode_cache appears as
SUnreclaim where in reality it should apper as SReclaimable.
This affect MemAvailable as well (it is lower than it should be).
