xfs: refactor log recovery EFI item dispatch for pass2 commit functions

Move the extent free intent and intent-done pass2 commit code into the
per-item source code files and use dispatch functions to call them.  We
do these one at a time because there's a lot of code to move.  No
functional changes.
