🐛 Bug Fixes

MmSupervisorPkg: Resolve uninitialized variable in V3 communication flow @makubacki (#608)

Change Details

Description

The code introduced in commiit f157378 trigers sometimes-uninitialized in the CLANGPDBG build because BufferSize is not initialized in a code path.

The code currently relies on ASSERT exclusively. This change adds error handling similar to other locations in the function to account for the case when asserts are disabled.
