[LMB]: Fix lmb_add_region if region should be added at the head
We introduced a bug in fixing lmb_add_region to handle an initial region being non-zero. Before that fix it was impossible to insert a region at the head of the list since the first region always started at zero. Now that its possible for the first region to be non-zero we need to check to see if the new region should be added at the head and if so actually add it.
