rcu: Fix rcu_torture_read ftrace event

Browse source 
commit d18a04157f 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;
