Subject: [PATCH 054/359] Monitor: fix for regression with container devices
References: bsc#1081910

This patch fixes 2 problems introduced by commit 9a518d8: not closing a
file descriptor and ignoring container devices. Array state is always
"inactive" for containers, so we make sure that the device is not a
container by reading also the "level" sysfs entry.
