ms/fuse: fuse_flush must check mapping->flags for errors
fuse_flush() calls filemap_write_and_wait() and checks
its status, but actual writeback will happen later, on
fuse_sync_writes(). If an error happens, fuse_writepage_end()
will set error bit in mapping->flags. So, we have to check
mapping->flags after fuse_sync_writes().
