Ansuel Smith e86dfd0a44 ipq806x: rework rootfs conflicts patch for smem
Now that smem actually free the leaked parts, when
a rootfs partition is detected, the kernel panics as
it try to free the static space allocated for the "ubi"
name. Change the logic and fix the name at the allocate_partition
function to correctly free the space allocated by smem.
