Anton Blanchard 0a93ea2e89 RxRPC: Allocate tokens with kzalloc to avoid oops in rxrpc_destroy
With slab poisoning enabled, I see the following oops:

  Unable to handle kernel paging request for data at address 0x6b6b6b6b6b6b6b73
  ...
  NIP [c0000000006bc61c] .rxrpc_destroy+0x44/0x104
  LR [c0000000006bc618] .rxrpc_destroy+0x40/0x104
  Call Trace:
  [c0000000feb2bc00] [c0000000006bc618] .rxrpc_destroy+0x40/0x104 (unreliable)
  [c0000000feb2bc90] [c000000000349b2c] .key_cleanup+0x1a8/0x20c
  [c0000000feb2bd40] [c0000000000a2920] .process_one_work+0x2f4/0x4d0
  [c0000000feb2be00] [c0000000000a2d50] .worker_thread+0x254/0x468
  [c0000000feb2bec0] [c0000000000a868c] .kthread+0xbc/0xc8
  [c0000000feb2bf90] [c000000000020e00] .kernel_thread+0x54/0x70

We aren't initialising token->next, but the code in destroy_context relies
on the list being NULL terminated. Use kzalloc to zero out all the fields.
