core/swap: follow the configured unit by default
Phenomenon: parameters configured in /etc/fstab for swap units are ignored. E.g. pri= settings have no effect when systemd starts swap units. What is even more confusing, .swap units for the name used in /etc/fstab initially show proper values for Priority=, but after starting them, they are re-initalized from /proc/swaps and show the -1 value from /proc/swaps. Change swap units to follow the original configured unit. This way proper settings are used when starting the swap.
