Commit changes for disks during do_phase(). Regular disks don't have changes
to save, but if we're replacing one disk with another disk, the replace object
is also a disk. Without this, the replace plugin's commit routine would never
get called and the replace would fail.

Apply with:
cd /usr/src/evms-2.4.0/
patch -p1 < commit.c.patch
