[PATCH] arm_pmu: Drop redundant armpmu->map_event() in armpmu_event_init()

[Anshuman Khandual <anshuman.khandual@arm.com>]

__hw_perf_event_init() already calls armpmu->map_event() callback, and also
returns its error code including -ENOENT, along with a debug callout. Hence
an additional armpmu->map_event() check for -ENOENT is redundant.
