NTFS: Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocks 

which is zero for a resident attribute but should no longer be zero
      once the attribute is non-resident as it then has real clusters
      allocated.

@ -43,6 +43,10 @@ ToDo/Notes:
reason we cannot simply read the size from the vfs inode i_size is
that this is not necessarily uptodate. This happens when
ntfs_attr_make_non_resident() is called in the ->truncate call path.
- Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocks
which is zero for a resident attribute but should no longer be zero
once the attribute is non-resident as it then has real clusters
allocated.
2.1.24 - Lots of bug fixes and support more clean journal states.
