Inga Stotland cffd5832a5 mesh: Tighten IO and fix out-of-bounds array access
This fixes the out-of-bounds array access in mesh-io-mgmt.c caught
by address sanitizer. Similar fixes were applied earlier to
generic and unit IOs. With this patch, the common code is factored
into a centralized location.
