[tkreuzer] 45062: [NTOS] KiExitV86Mode is supposed to return a pointer to the protected mode KTRAP_FRAME. Instead it was returning the value of TrapFrame->Edi, which would be identical to PmTrapFrame->Ebp, which doesn't have any particular meaning. Fix it by returning PmTrapFrame directly. Fixes 2nd stage boot.

KiExitV86Mode is supposed to return a pointer to the protected mode KTRAP_FRAME. Instead
it was returning the value of TrapFrame->Edi, which would be identical to
PmTrapFrame->Ebp, which doesn't have any particular meaning. Fix it by returning
PmTrapFrame directly. Fixes 2nd stage boot.
