Subject: Clean-up: sessiond: cmd: fix bogus -Wmaybe-uninitialized
X-Git-Tag: v2.13.0-rc1~74

Clean-up: sessiond: cmd: fix bogus -Wmaybe-uninitialized

Old gcc versions report:
cmd.c:4751: ‘query_target_action’ may be used uninitialized in this function [-Wmaybe-uninitialized]

For this to be reachable, a query target would have to change suddenly
during the execution of the function.
