Subject: MD removal and condition code bug

Radek Vykydal <rvykydal@redhat.com> encountered a problem with md devices. If 
the raid is about to be removed a "change" and "remove" event is sent.
The "change" event has to be skipped if ATTR{md/array_state} is empty, but 
somehow the condition does not match, which might point to a bug in the 
condition code.
The following patch is needed:

< ATTR{md/array_state}="|clear|inactive", GOTO="md_end"
---
 > ATTR{md/array_state}="clear|inactive", GOTO="md_end"
 > ATTR(md/array_state}!="?*", GOTO="md_end"
