[PATCH 5/6] krnl386: Fix return value for DPMI 0202h call (Get Processor Exception Handler Vector)

[Pali Rohár]

From: Pali Rohár <pali(a)kernel.org>

According to the DPMI specification, DPMI function 0202h call (Get
Processor Exception Handler Vector) sets the whole EDX register and not
only its low DX part.
