📄 Description

This addresses an issue with the ReleaseDirectMemory functions, where some games would hit an assert by calling them with len = 0. I also fixed an inaccurate error return in sceKernelMunmap (based on FreeBSD documentation), though I don't have any games that were hitting that error return.

This should fix some cases of [Debug] <Critical> memory.cpp:766 operator(): Assertion Failed!

This brings TerraTech (CUSA11362) ingame.
