*: update crossbeam-channel to avoid spin at sending side (#13807)

close #13815

According to crossbeam-rs/crossbeam#835, spinning at the
sending side is probably a bad idea because of large critical section and it's
fixed in the recent version.

This commit updates crossbeam-channel. It will reduce CPU usage a bit and
improve performance.
