f2fs: fix to check current blkaddr in __allocate_data_blocks
In __allocate_data_blocks, we should check current blkaddr which is located at ofs_in_node of dnode page instead of checking first blkaddr all the time. Otherwise we can only allocate one blkaddr in each dnode page. Fix it. Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
