mountstats: handle KeyError in accumulate_iostats()

This will prevent a backtrace like this from occurring in 'mountstats
nfsstat' if a new NFSv4 operation is added to the kernel but not to the
Nfsv4ops list in mountstats.py:

Traceback (most recent call last):
  File "/sbin/mountstats", line 988, in <module>
    res = main()
  File "/sbin/mountstats", line 977, in main
    return args.func(args)
  File "/sbin/mountstats", line 792, in nfsstat_command
    v4stats.accumulate_iostats(acc_stats)
  File "/sbin/mountstats", line 566, in accumulate_iostats
    self.__rpc_data[op] = list(map(add, self.__rpc_data[op],
new_stats.__rpc_data[op]))
KeyError: 'SEEK'
