Subject: drm/i915/gt: Flush the requests after wedging on suspend
Git-commit: 0cdfdf6fa9ee8babb72d3cb725c15a81dbc42bf1
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Retire all requests if we resort to wedged the driver on suspend. They
will now be idle, so we might as we free them before shutting down.
