DAFS: Raise LogLevel for per-chain vol stats

Only report detailed per-chain volume statistics on shutdown/SIGXCPU
if LogLevel is 125 (or 25 for smaller per-chain stats). If a
fileserver is configured with a large -vhashsize, printing out stats
for each chain can take awhile and use up a nontrivial amount of disk
space for logging, so only print out these stats if we're asked for
them.
