[PATCH 22/41] perf auxtrace arm: Fixing uninitialised variable

From: Mathieu Poirier <mathieu.poirier at linaro.org>

When working natively on arm64 the compiler gets pesky and complains
that variable 'i' is uninitialised, something that breaks the
compilation.  Here no further checks are needed since variable
'found_spe' can only be true if variable 'i' has been initialised as
part of the for loop.
