MdeModulePkg/EbcDebugger: Add missing check for symbol not found
In function DebuggerDisplaySymbolAccrodingToAddress(), when variable 'CandidateAddress' (returned by EbdFindSymbolAddress function) equals (UINTN) -1, it also indicates that the symbol is not found at the given address. This commit adds this missing check.
