Subject: [PATCH 2/2] systemd: account for unlocking failures in
clevis-luks-askpass
As unlock may fail for some reason, e.g. the network is not up yet,
one way cause problems would be to add extra `rd.luks.uuid' params
to the cmdline, which would then cause such devices to be unlocked
in early boot. If the unlocking fail, those devices might not be
accounted for in the clevis_devices_to_unlock() check, as it is
based on crypttab.
Let's make sure there are no pending ask.* sockets waiting to be
answered, before exiting.
