fuse: don't ignore errors from fuse_writepages_fill() 

[ Upstream commit 7779b047a5 ]

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: 26d614df1d ("fuse: Implement writepages callback")
