fuse: Flush files on wb close
Any write request requires a file handle to report to the userspace. Thus when we close a file (and free the fuse_file with this info) we have to flush all the outstanding dirty pages. filemap_write_and_wait() is enough because every page under fuse writeback is accounted in ff->count. This delays actual close until all fuse wb is completed. In case of "write cache" turned off, the flush is ensured by fuse_vma_close().
