Gao Xiang 5500221ea1 ext4: bio_alloc with __GFP_DIRECT_RECLAIM never fails 
Similar to [1] [2], bio_alloc with __GFP_DIRECT_RECLAIM flags
guarantees bio allocation under some given restrictions, as
stated in block/bio.c and fs/direct-io.c So here it's ok to
not check for NULL value from bio_alloc().
