keys: fix trusted/encrypted keys sparse rcu_assign_pointer messages
Define rcu_assign_keypointer(), which uses the key payload.rcudata instead
of payload.data, to resolve the CONFIG_SPARSE_RCU_POINTER message:
"incompatible types in comparison expression (different address spaces)"
Replace the rcu_assign_pointer() calls in encrypted/trusted keys with
rcu_assign_keypointer().
