[PATCH 15/22] pnfs_submit: remove pnfs_file_operations

[Fred Isaman <iisaman@netapp.com>]

pnfs_writepages is useful, but not necessary, for determining size
parameters for LAYUTGET.

Also, the pnfs_file_operations were getting out of sync with
nfs_file_operations (see commits e1ebfd33be068 and bf40d3435caf49369).
