Sorry, but that's really stupid.  If people have the arrays that have
device handlers there are two possible cases:

 - just a single port configured on the array. In this case the device
   handlers are useless but also completely unharmful.
 - multiple ports configured on the array.  In this case we desperately
   want the device handlers loaded early so that we do the right thing
   for the inactive ports and avoid the horrible probing delays, not
   matter if we actually do end up using multipath later or no.

No need to make this configurable.  If people really do not want the
handler (e.g. becuase the may end up beeing buggy for a new array
matching the old idea) they can just blacklist it in the modules
configuration.
