ARM: perf: remove useless return and check of idx in counter handling

Browse source

Idx sanity check was once implemented separately in these counter
handling functions and then return value was treated as a judgement.
	armv7_pmnc_select_counter()
	armv7_pmnc_enable_counter()
	armv7_pmnc_disable_counter()
	armv7_pmnc_enable_intens()
	armv7_pmnc_disable_intens()
But we do not need to do this now, as idx validation check was moved
out all these functions by commit 7279adbd9bb8ef8f(ARM: perf: check ARMv7
counter validity on a per-pmu basis).
Let's remove the useless return of idx from these functions.
