[PATCH 1/3] nfsstat: The --list option does not work on server stats.

[Steve Dickson <SteveD@redhat.com>]

The print_stats_list() routine was using the client's
stats to decide whether to display any stats. This did
not work when there was only server stats.
    
This patch breaks up print_stats_list into two different
routines allowing both server and clients stats to be
listed.
