block: make rq_init() do a full memset()
This requires moving rq_init() from get_request() to blk_alloc_request().
The upside is that we can now require an rq_init() from any path that
wishes to hand the request to the block layer.
rq_init() will be exported for the code that uses struct request
without blk_get_request.
This is a preparation for large command support, which needs to
initialize struct request in a proper way (that is, just doing a
memset() will not work).
