Log Message:
dm: Make target's ->table() optional

Since ->info() (counter part of ->table() in the original dm design
in Linux kernel in .status where both INFO and TABLE are optional)
is an optional handler, make ->table() optional as well. Some
targets don't have anything to do in ->table() just as in ->info().
