fs/ntfs3: zero newly allocated clusters when the request is smaller than the frame

For compressed attributes, allocation is rounded up to a whole
compression frame, so a request covering only part of a frame still
allocates clst_per_frame clusters. The clusters outside the requested
range are then allocated but never written by the caller.

Until now 'zero' was set only when allocation had to start before the
requested VCN. When it started at vcn0 but extended past the end of
the request, the tail clusters were left holding whatever was
previously on disk.
