[libvirt] [PATCH] Avoid Coverity DEADCODE warning

[John Ferlan]

Commit '922b7fda' resulted in two DEADCODE warnings from Coverity in
remoteDispatchAuthPolkit and virAccessDriverPolkitFormatProcess.
Commit '604ae657' modified the daemon.c code to remove the deadcode
issue, but did not do so for viracessdriverpolkit.c. This just mimics
the same changes
