[btrfs] fix check_direct_IO() for non-iovec iterators looking for duplicate ->iov_base makes sense only for iovec-backed iterators; for kvec-backed ones it's pointless, for bvec-backed ones it's pointless and broken on 32bit (we walk through an array of struct bio_vec accessing them as if they were struct iovec; works by accident on 64bit, but on 32bit it'll blow up) and for pipe-backed ones it's pointless and ends up oopsing.
