[PATCH] 64-md-raid.rules fixes v2

[Michal Soltys <soltys@ziu.info>]

1) introduced in commit b822542608326092e177fd1707ca7fb53b2846c4

md/array_state in case of partition doesn't exists, so all uevents
for partitions didn't execute any SYMLINK rules

2) add compat rule, so both MD_DEVNAME (mdadm 3.0) and MD_NAME
   (mdadm 2.9.x) can be used
