Amery Hung says:

====================
Use kmalloc_nolock() universally in BPF local storage

Socket local storage did not convert to use kmalloc_nolock() since there
were observable performance degredation due to kfree_nolock() hitting the
slow path and the lack of kfree_rcu()-like batching freeing. Now that
these concern were addressed in slub, convert all remaining local storage
flavors to use kmalloc_nolock().

v1 -> v2:
  - Fix build (CI, Alexei)
