st/mesa: Clear texture's views when texture is removed from Shared->TexObjects

Browse Source 
If texture is shared between several contexts, calling glDeleteTextures
will remove it from ctx->Shared->TexObjects - which makes impossible for
contexts, when destroyed, to release their views to this texture. Which
leaves dangling pointers to destroyed contexts.
