[edk2-devel] [PATCH 2/2] StandaloneMmPkg: Initialize 'WillReturn' variable

["Zhiguang Liu" <zhiguang.liu@intel.com>]

The local variable 'WillReturn' was being used without prior
initialization in some code paths.
This patch ensures that 'WillReturn' is properly initialized
to prevent undefined behavior.
