Fix warnings about uninitialized variables
qtbase/src/corelib/kernel/qmetatype.cpp: In static member function ‘static void QMetaType::destroy(int, void*)’:
qtbase/src/corelib/kernel/qmetatype.cpp:2599:27: error: ‘info.QMetaType::m_destructor’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
if (m_typedDestructor && !m_destructor)
~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~
qtbase/src/corelib/kernel/qmetatype.cpp:1868:15: note: ‘info.QMetaType::m_destructor’ was declared here

qtbase/src/corelib/kernel/qmetatype.cpp:2600:26: error: ‘info.QMetaType::m_typedDestructor’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~
qtbase/src/corelib/kernel/qmetatype.cpp:1868:15: note: ‘info.QMetaType::m_typedDestructor’ was declared here

The extended (not inlined) function may be called on a half
initialized invalid instance.
