elog: Get rid of elog_reinit_descriptor.
This function was just a wrapper around elog_init_descriptor, and all it did was pass the current backing store location and size back in so it would be reused. Those values, which never change, are now set in elog_setup_descriptors, eliminating those parameters to init and eliminating the need for _reinit_. Built and booted on Link. Ran mosys eventlog list. Added 2000 events to the log and ran mosys eventlog list again.
