[PATCH] MdeModulePkg/SmmLockBoxLib: Remove dead code

[icegambit91@gmail.com]

Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=4317

The "if" condition on line 554 ensures that Guid won't be NULL (or 0) on line 600.
So, there will never be a situation where the "else" block on line 603 is executed.
