Subject: [PATCH mm 10/22] kasan: move disable_trace_on_warning to start_report

From: Andrey Konovalov <andreyknvl@google.com>

Move the disable_trace_on_warning() call, which enables the
/proc/sys/kernel/traceoff_on_warning interface for KASAN bugs,
to start_report(), so that it functions for all types of KASAN reports.
