fuse: cleanup code conditional on fc->writeback_cache
It's safe to call file_update_time() if writeback cache is not enabled, since S_NOCMTIME is set in this case. This part is purely a cleanup. __fuse_copy_file_range() also calls fuse_write_update_attr() only in the writeback cache case. This is inconsistent with other callers, where it's called unconditionally. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
