Al Viro 67d1214551 merge task_work and rcu_head, get rid of separate allocation for keyring case ...

task_work and rcu_head are identical now; merge them (calling the result
struct callback_head, rcu_head #define'd to it), kill separate allocation
in security/keys since we can just use cred->rcu now.
