Fix T84565: UV face select fails when zoomed in

Exposed by recent commit 246efd7286f6187e4dd4b3edcc79cccb1746bb1d

Although this was an existing logical error causing
`uv_find_nearest_face` to only work properly when the hit distance was
initialized to FLT_MAX, which wasn't the case in multi-object edit mode.
