PEL: Move down quiesce check
PEL: Move down quiesce check

Move the check where the host quiesce target may get started based on
the PEL severity to the last thing that happens when either a PEL is
created by BMC code or received by the host.  It just seems more
straight forward to not start systemd targets before even filling in all
of the PEL related D-Bus properties.
