rcu: Fix rcu_torture_read ftrace event

Browse Source 
commit d18a04157fc171fd48075e3dc96471bd3b87f0dd upstream.

Fix the rcutorturename field so that its size is correctly reported in
the text format embedded in trace.dat files. As it stands, it is
reported as being of size 1:

    field:char rcutorturename[8];   offset:8;       size:1; signed:0;
