[Bug 1821261] [NEW] nfsiostat broken and exits with traceback

[Matthew Ruffell]

Public bug reported:

nfsiostat, in nfs-common-1.3.4-2, is broken in bionic, cosmic and disco.

When you run the command nfsiostat, either as root or a regular user,
the following traceback is printed:

$ nfsiostat
Traceback (most recent call last):
  File "/usr/sbin/nfsiostat", line 640, in <module>
    iostat_command(prog)
  File "/usr/sbin/nfsiostat", line 593, in iostat_command
    devices = list_nfs_mounts(origdevices, mountstats)
  File "/usr/sbin/nfsiostat", line 495, in list_nfs_mounts
    for device, descr in list(mountstats.items()):
TypeError: 'list' object is not callable

This is caused by the 'list' reserved word being used as a variable name
in list_nfs_mounts(), and is explained here:

on-18-04/1123336#1123336?s=a1e9150fbf284e849efe6fe084e7c7b8

I will send a patch to upstream shortly, and begin the SRU process. It's
going to be my first SRU since I started in sts-eng, so that's exciting.
