📄 Description

Return ENOMEM if len exceeds the available space in sceKernelMapNamedDirectMemory.

This is based on a hardware test, courtesy of a plugin by @StevenMiller123. It fixes a discrepancy found in Driveclub if you use the CLI flag -increasedrenderplus, and with this PR, the console and the emulator now crash at the same place.

Klog:

<118>(../dmem/source/main.c:49) sceKernelMapDirectMemory called, in_addr = 2000000000, len = fffffffff8a00000, flags = 0, phys_addr = 0, align = 200000
<118>(../dmem/source/main.c:51) sceKernelMapDirectMemory called, out_addr = 2000000000, result = 8002000c
