drbd: revert "delay probes", feature is being re-implemented differently
It was a now abandoned attempt to throttle resync bandwidth based on the delay it causes on the bulk data socket. It has no userbase yet, and has been disabled by 9173465ccb51c09cc3102a10af93e9f469a0af6f already. This removes the now unused code. The basic feature, namely using up "idle" bandwith of network and disk IO subsystem, with minimal impact to application IO, is being reimplemented differently.
