Subject: drm/i915/gem: Manually dump the debug trace on GEM_BUG_ON
Git-commit: 8ad305f1a29a8c06586aaef87443ce14936aac30
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Since igt now defaults to not enabling ftrace-on-oops, we need to
manually invoke GEM_TRACE_DUMP() to see the debug log prior to a
GEM_BUG_ON panicking.
