Matthew Wilcox (Oracle) fc99f4e2d2 ubifs: Set page uptodate in the correct place 
[ Upstream commit 723012cab779eee8228376754e22c6594229bf8f ]

Page cache reads are lockless, so setting the freshly allocated page
uptodate before we've overwritten it with the data it's supposed to have
in it will allow a simultaneous reader to see old data.  Move the call
to SetPageUptodate into ubifs_write_end(), which is after we copied the
new data into the page.

Fixes: 1e51764a3c2a ("UBIFS: add new flash file system")
