[v2,03/15] umh: Rename the user mode driver helpers for clarity

Commit Message

Eric W. Biederman June 29, 2020, 7:57 p.m. UTC

Now that the functionality of umh_setup_pipe and
umh_clean_and_save_pid has changed their names are too specific and
don't make much sense.  Instead name them  umd_setup and umd_cleanup
for the functional role in setting up user mode drivers.
