networkd: keep static lease section valid on MACAddress= reset

config_parse_dhcp_static_lease_hwaddr() uses a cleanup helper that marks
a lease section invalid unless ownership is taken.

Add TAKE_PTR(lease) on the empty-rvalue reset path so subsequent valid
MACAddress= assignments in the same section are not dropped.
