virsh: Remove unnecessary else branches

Browse Source 
In a few cases we call a public API, wrapped in an if() statement
with both branches written out explicitly. The error branch jumps
onto cleanup label, while the successful prints out a message.
Right after these ifs there's 'ret = true;' and the cleanup
label. The code is a bit more readable if only the error branch
is kept and printing happens at the same level as setting the ret
variable.
