Description of problem:
Segmentation fault when run some virt-admin help srv* cmd.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.install libvirt-admin pkg
2.# virt-admin help srv-clients-set
srv-clients-set - (null)
Segmentation fault (core dumped)
same with cmd srv-threadpool-set,srv-clients-info,srv-threadpool-info,srv-clients-list
actually srv-* cmd removed in help contents.
Monitoring commands (help keyword 'monitor'):
server-list list available servers on a daemon
server-threadpool-info get server workerpool parameters
client-list list clients connected to <server>
client-info retrieve client's identity info from server
server-clients-info get server's client-related configuration limits
Management commands (help keyword 'management'):
server-threadpool-set set server workerpool parameters
client-disconnect force disconnect a client from the given server
server-clients-set set server's client-related configuration limits
daemon-log-filters fetch or set the currently defined set of logging filters on daemon
daemon-log-outputs fetch or set the currently defined set of logging outputs on daemon
if virt-admin use server* instead of srv*, we hope no Segmentation fault and
error msg like this:
error: command or command group 'srv*' doesn't exist

vsh: Cmd aliases lookups should return results for the aliased command
Unfortunately, we have a number of aliases in virsh and even though
these are not visible any more, we have to support them. The problem is
that when trying to print help for the alias, we get SIGSEGV because
there isn't any @def structure anymore and we need to query the command
being aliased instead.

Verify this bug with:
1. print help for virsh cmd alias
# virsh help nodedev-dettach
nodedev-detach - detach node device from its device driver
nodedev-detach <device> [--driver <string>]
2. print help for virt-admin cmd alias
# virt-admin help srv-list
server-list - list available servers on a daemon
I also try to print help other cmd aliases of virt-admin, including srv-threadpool-info, srv-clients-info, srv-threadpool-set, srv-clients-set, all of them work well.
As the result matches with the expected result, mark the bug as verified.
