Emulate memory behavior of libSceGnmDriver initialization (#2807)

Browse source 
* Emulate memory behavior of libSceGnmDriver _DT_INIT

Due to the unique way some games check for sceKernelAllocateDirectMemory failures, emulating this properly is necessary.

* Clang

* Fix address input for direct memory call

* Fix bug with DirectQueryAvailable

Missed this in my prior PR.

* DirectQueryAvailable fix

Fixes error cases to be more hardware accurate.
