Ingo Molnar c6ef89421e x86/idt: Fix the X86_TRAP_BP gate
Andrei Vagin reported a CRIU regression and bisected it back to:

  90f6225fba ("x86/idt: Move IST stack based traps to table init")

This table init conversion loses the system-gate property of X86_TRAP_BP
and erroneously moves it from DPL3 to DPL0.

Fix it.
