Bug 1033697 - Remove dead code from XPCConvert::NativeInterface2JSObject; r=bholley
Earlier in the function, there is an always-returning branch if |flat| is
non-null, so this code is only reached with a null |flat|, and the removed
code is dead.
Bug 1033697 - Remove the temporary variable 'v' from XPCConvert::NativeInterface2JSObject; r=bholley
There is no good reason to keep the additional local variable, especially
because it is only used inside this branch.
