------------------------------------------------------
From: Aymeric Agon-Rambosson <aymeric.agon@xxxxxxxxxx>
Subject: scripts/gdb: repair rb_first() and rb_last()

The current implementations of the rb_first() and rb_last() gdb functions
have a variable that references itself in its instanciation, which causes
the function to throw an error if a specific condition on the argument is
met.  The original author rather intended to reference the argument and
made a typo.  Referring the argument instead makes the function work as
intended.
