Title: Fixing logical error in detecting virtual device.

Redoing my pull request:

So In my Centos 5.9 machine, if there is RAID mount ansible will crash, as it cannot find scheduler file. The reason being, this should be a virtual device as there is no "device" folder under e.g. /sys/block/md0/

Here is the crash:

[kk@u1 ansible]$ ansible q3 -m setup -k -u root --tree=/tmp/facts
SSH password:
q3 | FAILED => failed to parse: /sys/block/md0
Traceback (most recent call last):
