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.
