Chao Yu 75cd4e098d f2fs: support FALLOC_FL_ZERO_RANGE 
Now, FALLOC_FL_ZERO_RANGE flag in ->fallocate is supported in ext4/xfs.

In commit, the semantics of this flag is descripted as following:"
1) Make sure that both offset and len are block size aligned.
2) Update the i_size of inode by len bytes.
3) Compute the file's logical block number against offset. If the computed
   block number is not the starting block of the extent, split the extent
   such that the block number is the starting block of the extent.
4) Shift all the extents which are lying between
   [offset, last allocated extent] towards right by len bytes. This step
   will make a hole of len bytes at offset."

This patch implements fallocate's FALLOC_FL_ZERO_RANGE for f2fs.
