uvcvideo: Fix crash when linking entities

commit 4d9b2ebd335d83044b9e6656d0e604e8e1300334 upstream.

The uvc_mc_register_entity() function wrongfully selects the
media_entity associated with a UVC entity when creating links. This
results in access to uninitialized media_entity structures and can hit a
BUG_ON statement in media_entity_create_link(). Fix it.
