selftests/resctrl: Move ->setup() call outside of test specific branches

Browse source 
[ Upstream commit c90b3b588e369c20087699316259fa5ebbb16f2d ]

resctrl_val() function is called only by MBM, MBA, and CMT tests which
means the else branch is never used.

Both test branches call param->setup().

Remove the unused else branch and place the ->setup() call outside of
the test specific branches reducing code duplication.
