mdadm error

Hi,

If mdadm.conf has configured devices which do not exist, then logwatch will
print:

--------------------- Mdadm Begin ------------------------ 

 mdadm: cannot open /dev/md0: No such file or directory  Can't use an
undefined value as an ARRAY reference at
/usr/share/logwatch/scripts/services/mdadm line 83.
 /dev/md0 : 
 
 ---------------------- Mdadm End ------------------------- 

This is only printed for the first invalid device.
The attached patch checks for this error and prints the "No such file or
directory error" for all invalid devices without the undefined value error.

Regards,
gulikoza
