fuse: don't ignore errors from fuse_writepages_fill()
[ Upstream commit 7779b047a57f6824a43d0e1f70de2741b7426b9d ]
fuse_writepages() ignores some errors taken from fuse_writepages_fill() I
believe it is a bug: if .writepages is called with WB_SYNC_ALL it should
either guarantee that all data was successfully saved or return error.
Fixes: 26d614df1da9 ("fuse: Implement writepages callback")
