[clang-format][NFC] Simplify if in ContinuationIndenter::addTokenOCL

[HazardyKnusperkeks]

Summary

Setting a boolean within an if and only using it in the very next if is a bit confusing. Merge it into one if.

clang/lib/Format/ContinuationIndenter.cpp

void ContinuationIndenter::addTokenOnCurrentLine(LineState &State, bool DryRun,
   } else if (Current.is(TT_CSharpGenericTypeConstraintColon)) {
     CurrentState.ColonPos = State.Column;
   } else if (Previous.opensScope()) {
     // If a function has a trailing call, indent all parameters from the
     // opening parenthesis. This avoids confusing indents like:
     //   OuterFunction(InnerFunctionCall( // break
     //       ParameterToInnerFunction))   // break
     //       .SecondInnerFunctionCall();
-    bool HasTrailingCall = false;
     if (Previous.MatchingParen) {
       const FormatToken *Next = Previous.MatchingParen->getNextNonComment();
-      HasTrailingCall = Next && Next->isMemberAccess();
-    }
-    if (HasTrailingCall && State.Stack.size() > 1 &&
+      if (Next && Next->isMemberAccess() && State.Stack.size() > 1 &&
           State.Stack[State.Stack.size() - 2].CallContinuation == 0)
         CurrentState.LastSpace = State.Column;
     }
   }
+}
