Subject: fault-injection: skip stacktrace filtering by default
Date: Wed, 17 Aug 2022 08:03:30 +0000

If FAULT_INJECTION_STACKTRACE_FILTER is enabled, the depth is default to
32.  This means fail_stacktrace() will iter each entry's stacktrace, even
if filter is not configured.

This patch changes to quick return from fail_stacktrace() if stacktrace
filter is not set.
