Per the documentation, is_selinux_enabled() returns -1 on error. Account
for this. Previously when -1 was being returned the condition would
still be true. I was noticing this because on my system that has selinux
disabled I was getting this in the libvirt.log every 5 seconds:
error : virIdentityGetSystem:173 : Unable to lookup SELinux process
context: Invalid argument
With this patch applied, I no longer get these messages every 5 seconds.
I am submitting this in case its deemed useful for inclusion. Anyone
have any comments on this change? This is a patch off current master.
