Subject: drm/i915/gt: Hook up intel_context_fini()
Git-commit: df8cf31e749788d8de8c3028e530e6fd9ef8bc79
Patch-mainline: v5.4-rc1
References: bsc#1152489

Prior to freeing the struct, call the fini function to cleanup the
common members. Currently this only calls the debug functions to mark
the structs as destroyed, but may be extended to real work in future.
