Description of problem:
When an audit rule without a field is added, auditctl will append a "No rules"
message to the list.

Version-Release number of selected component (if applicable):
audit-0.7.1-1

How reproducible:
always

Steps to Reproduce:

# auditctl -D
No rules

# auditctl -a exit,always -S open
AUDIT_LIST: exit always syscall=open
No rules

# auditctl -l
AUDIT_LIST: exit always syscall=open
No rules

# auditctl -a exit,always -S open -F success=0
AUDIT_LIST: exit always syscall=open
AUDIT_LIST: exit always success=0 syscall=open

# auditctl -l
AUDIT_LIST: exit always syscall=open
AUDIT_LIST: exit always success=0 syscall=open

  
Actual results:
The first list command's result ends with a "No rules" message.

Expected results:
Only the rule should be listed, as is the case when the second rule is added.
