Description
Currently, the error code of urVirtualMemMap is invalid argument when the VA is already mapped.
But this error code is not clear enough, since returning invalid argument could also be due to other reasons, like the size is not proper.

Research direction
Start by tracing the urVirtualMemMap entry point and its existing invalid-argument handling. Review how error codes are defined and tested in the repository; the work is done when an already-mapped VA produces a distinct error code without changing other invalid-argument cases.
