Subject: [PATCH] ARM: perf: remove useless return and check of idx in counter
 handling

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.
