Address the cases where submitter is also the maintainer of the code changed and other areas are being changed. In this case, assign to the next area maintainers instead of assigning to submitter. Example: maintainer of component A introduced significant changes to area A but also makes changes to other areas B and C. Right now maintainers of B and C are added as reviewers. This change will assign to the next area after A, i.e. B in cases where the submitter is also the maintainer of area A. Signed-off-by: Anas Nashif <anas.nashif@intel.com>
