Subject: [PATCH] Fix uninitialized vars in EnumDeclaration

'protection' and 'parent' are used in ScopeDSymbol::search
detected by Valgrind). The assignment in semantic0 is enough to
fix the bug, but I also added an initialization to the constructor.

This is a backport of DMD commit 4dfaf02d4d by Don Clugston.
