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.
