exit/bdflush: Remove the deprecated bdflush system call

2021-07-12T20:17:47Z

The bdflush system call has been deprecated for a very long time. Recently Michael Schmitz tested[1] and found that the last known caller of of the bdflush system call is unaffected by it's removal. Since the code is not needed delete it.
