From: Darrick J. Wong <darrick.wong@oracle.com>

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.

EFI/EFD item pass2 processing is functionally consistent with what was done
before this patch is applied.
