Subject: [PATCH] Fix compiler warnings in matrix.cpp

Add a return clause, because assert() may be replaced with nothing by
the preprocessor under -DNDEBUG.

matrix.cpp: In member function 'std::vector<Integer> libnormaliz::Matrix<Integer>::VxM_div(const
std::vector<Integer>&, const Integer&, bool&) const [with Integer = double]':
matrix.cpp:942:1: warning: no return statement in function returning non-void [-Wreturn-type]
matrix.cpp:2262:1: warning: no return statement in function returning non-void [-Wreturn-type]
matrix.cpp:2696:1: warning: no return statement in function returning non-void [-Wreturn-type]
