Timo Kreuzer 690fd6eb6d [NTOS] Allocate the trap frame on the stack by decreasing esp before modifying any members.
While doing it after is a tiny optimization (no need to wait for esp to be ready) and would work with all real traps (which clear cli), it doesn't work with Zw calls that directly call KiSystemService with interrupts enabled. This caused random trap frame corruption when an interrupt fired after members of the trap frame have been set but before esp was adjusted. Should hopefully fix most random failures on real hardware and qemu.
