isdn: Convert obsolete cputime type to nsecs

Not sure if MISDN stats are ABI but it displays task cputime in cputime_t
raw value regardless of what type cputime_t wraps which could be either
jiffies, nsecs, usecs, or whatever random time unit. Plus it wrongly
assumes that cputime_t is long.

Given that this dump is broken anyway, lets just display the nanosec
value and stick with that.
