block: push BKL into blktrace ioctls
The blktrace driver currently needs the BKL, but
we should not need to take that in the block layer,
so just push it down into the driver itself.
It is quite likely that the BKL is not actually
required in blktrace code and could be removed
in a follow-on patch.
