[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.
