mm: memcontrol: give the kmem states more descriptive names
On any given memcg, the kmem accounting feature has three separate states: not initialized, structures allocated, and actively accounting slab memory. These are represented through a combination of the kmem_acct_activated and kmem_acct_active flags, which is confusing. Convert to a kmem_state enum with the states NONE, ALLOCATED, and ONLINE. Then rename the functions to modify the state accordingly. This follows the nomenclature of css object states more closely.
