[PATCH 3/3] perf tools: Fixing uninitialised variable

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.
