dyndbg: drop EXPORTed dynamic_debug_exec_queries

[ Upstream commit e26ef3af964acfea311403126acee8c56c89e26b ]

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: 4c0d77828d4f ("dyndbg: export ddebug_exec_queries")
