[ROSTESTS] Pipes creation fails 4 of 5 times in a little test developed for Kernel32.

ROS version tested: ReactOS bootcd-0.4.16-dev-624-gefdda7f-x86-gcc-lin-dbg
Context: VirtualBox 7
RAM: 1024 MB
HDD: 4 GB
Software tested: Artifacts from Simone's and mine's Pipe fix PR 6724
Test binary (x86 and x64)attached.

Description of the bug: Execute in CMD "kernel32_apitest.exe Pipes" more than 5 times in a row (pressing up and enter relatively fast) the binary attached. One of each, the test will pass as it should, despite of the other 4, that will fail under ReactOS with the error 0x218, always affecting the big buffer.

The debug log is not showing so much information about it. Surely I can enable Kernel32 debug flags and some MM/CC / NTOSKRNL too, if any of them give me clues about what the hell is failing.

Situation under Windows/Wine: No failure in that execution in the row of 5.

Here is the screenshot with the error quoted (3 failures) and the "expected" (1 failure) that is the one that fixes the PR (not apitest code).
