The operations performed from XFS_DAS_FOUND_LBLK through to
XFS_DAS_RM_LBLK are now identical to XFS_DAS_FOUND_NBLK through to
XFS_DAS_RM_NBLK. We can collapse these down into a single set of
code.
To do this, define the states that leaf and node run through as
separate sets of sequential states. Then as we move to the next
state, we can use increments rather than specific state assignments
to move through the states. This means the state progression is set
by the initial state that enters the series and we don't need to
duplicate the code anymore.
At the exit point of the series we need to select the correct leaf
or node state, but that can also be done by state increment rather
than assignment.
