Wei Yongjun 4acb9e5139 fault-injection: skip stacktrace filtering by default
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.
