dyndbg: drop EXPORTed dynamic_debug_exec_queries
This exported fn is unused, and will not be needed. Lets dump it.
The export was added to let drm control pr_debugs, as part of using
them to avoid drm_debug_enabled overheads. But its better to just
implement the drm.debug bitmap interface, then its available for
everyone.
Fixes: a2d375eda771 ("dyndbg: refine export, rename to dynamic_debug_exec_queries()")
Fixes: 4c0d77828d4f ("dyndbg: export ddebug_exec_queries")
