Fix for EXT-2836 (Changing texture on Media on a Prim face removes MoaP functionality).

LLVOVolume::regenFaces() (specifically the calls to facep->setTexture()) breaks associations between faces and LLViewerMediaTexture objects when called on a prim with playing media.

This change adds code which recreates the associations.
