mm: vmalloc: remove global purge_vmap_area_root rb-tree
Similar to busy VA, lazily-freed area is stored to a node it belongs to.
Such approach does not require any global locking primitive, instead an
access becomes scalable what mitigates a contention.
This patch removes a global purge-lock, global purge-tree and global purge
list.
