NFS: Remove all NFSIOS_FSCACHE counters due to conversion to netfs API
The old NFSIOS_FSCACHE counters are no longer accurate or useful with
the conversion to the new netfs API. The new API does not have a page
based interface, and so the counters in nfs_stat_fscachecounters are
no longer obtainable. The new netfs the API has extensive statistics
inside /proc/fs/fscache/stats so we no longer need NFS specific fscache
stats.
Note this also removes the 'fsc:' line from /proc/self/mountstats so
it will be a user-visible change.
