Subject: [PATCH] rcutorture: don't mark torture_init_{begin,end} with __init

By the time rcutorture is initialised via its module_init callback, the
.init.text section of torture.ko has already been freed, so the calls to
torture_init{begin,end} end up branching to junk.

This patch removes the __init annotations from torture_init_{begin,end}
to make sure the code is there when we want to call it.

Just lost a day to this -- I was sure my static relocation handling must
be to blame!
