ARM: 9406/1: Fix callchain_trace() return value
[ Upstream commit 4e7b4ff2dcaed228cb2fb7bfe720262c98ec1bb9 ]
perf_callchain_store() return 0 on success, -1 otherwise, fix
callchain_trace() to return correct bool value. So walk_stackframe() can
have a chance to stop walking the stack ahead.
Fixes: 70ccc7c0667b ("ARM: 9258/1: stacktrace: Make stack walk callback consistent with generic code")
