[PATCH 4/6] krnl386: Fix reporting error code for DPMI 0102h call (Resize DOS Memory Block)

[Pali Rohár]

From: Pali Rohár

According to the DPMI specification, when DPMI function 0102h (Resize DOS
Memory Block) fails then AX has to be set to error code and BX to maximum
possible block size.

As the wine does not implement the DPMI function 0102h (Resize DOS Memory
Block), set the error code to 0x0008 (insufficient memory) and maximum
possible block size to 0 (no memory available).
