Al Viro 79762247b6 nfs_write_end(): fix handling of short copies 
[ Upstream commit c0cf3ef5e0 ]

What matters when deciding if we should make a page uptodate is
not how much we _wanted_ to copy, but how much we actually have
copied.  As it is, on architectures that do not zero tail on
short copy we can leave uninitialized data in page marked uptodate.
