selftests/resctrl: Unmount resctrl FS if child fails to run benchmark

Browse source

[ Upstream commit f99e413eb5 ]

A child calls PARENT_EXIT() when it fails to run a benchmark to kill
the parent process. PARENT_EXIT() lacks unmount for the resctrl FS and
the parent won't be there to unmount it either after it gets killed.

Add the resctrl FS unmount also to PARENT_EXIT().
