Maxim Patlasov 6c49d77a82 fuse: fuse_flush must check mapping->flags for errors 
commit 9ebce595f6 upstream.

fuse_flush() calls write_inode_now() that triggers writeback, 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().
