Alberto Garcia 3e4c5122cb block: Block all nodes involved in the block-commit operation 
After a successful block-commit operation all nodes between top and
base are removed from the backing chain, and top's overlay needs to
be updated to point to base. Because of that we should prevent other
block jobs from messing with them.

This patch blocks all operations in these nodes in commit_start().
