block: Remove REQ_KERNELfor-3.18/core
REQ_KERNEL is no longer used. Remove it and drop the redundant uio argument to nfs_file_direct_{read,write}. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Cc: Christoph Hellwig <hch@infradead.org> Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jens Axboe <axboe@fb.com>
