The cumulative counter (object 0x1C0B/0x01) doesn't count lost SoC
frames correctly. It stops counting logical SoC losses after the first
logical loss, and then only counts SoC timeouts. With this commit,
the counting continues without limits in case of logical SoC losses.
However, lost SoA frames will not be counted any more, if the CN waits
for an SoA frame and an SoC timeout occurs.
