Reset provider's texture if QQuickNiniPatchImage's source is invalid
When QQuickNinePatchImage is used as a source of other shader related
object like ShaderEffect, OpacityMask or etc.,
there isn't a implementation to invalidate the provider's texture
when QQuickNinePatchImage is invalid.
It causes segmentation fault due to dangling pointer.
Fixes: QTBUG-100508
