[Accel-config] [PATCH v1 2/5] accel-config: Make command handler return status instead of exiting out

From: Ramesh Thomas <ramesh.thomas(a)intel.com>

Make main_handle_internal_command() return a value indicating status
instead of exiting out directly. This will allow post processing after
handling commands.
