The allocation-state indicator should only actually be implemented for
"logical" DRCs, not physical ones. Factor a check for this, and also for
valid indicator state values into rtas_set_allocation_state(). Because
they don't exist for physical DRCs, there's no reason that we'd ever want
more than one method implementation, so it can just be a plain function.
In addition, the setting to USABLE and setting to UNUSABLE paths in
set_allocation_state() don't actually have much in common. So, split the
method separate functions for each parameter value (drc_set_usable()
and drc_set_unusable()).
