[PATCH 2/4] selftests/resctrl: Move ->setup() call outside of test specific branches

[Ilpo Järvinen <ilpo.jarvinen@xxxxxxxxxxxxxxx>]

resctrl_val() function is called only by mbm, mba, and cmt tests which
means the else branch is never used and can be removed.

Presently, both of the the test branches call param->setup(). Thus, the
call can be placed outside of the test specific branches reducing code
duplication.
