xfs: remove some obsolete comments in xfs_trans_ail.c

/*

 * The active item list (AIL) is a doubly linked list of log

 * items sorted by ascending lsn.  The base of the list is

 * a forw/back pointer pair embedded in the xfs mount structure.

 * The base is initialized with both pointers pointing to the

 * base.  This case always needs to be distinguished, because

 * the base has no lsn to look at.  We almost always insert

 * at the end of the list, so on inserts we search from the

 * end of the list to find where the new item belongs.

/*

 * Initialize the doubly linked list to point only to itself.
