Subject: [PATCH 125/132] perf auxtrace arm: Fixing uninitialised variable

Git-commit: d2785de15f1bd42d613d56bbac5a007e7293b874
Patch-mainline: v4.17-rc1
References: fate#325865,fate#325861

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.
