[PATCH 3/7] nfs41: remove uneeded checks in callback processing

[andros@netapp.com]

From: Andy Adamson <andros@netapp.com>

All callback operations have arguments to decode and require processing.
The preprocess_nfs4X_op functions catch unsupported or illegal ops so
decode_args and process_op pointers are always non NULL.
