NFSv4: Check the return value of decode_compound_hdr_arg()

Browse source

If decode_compound_hdr_arg() returns a resource error, then we cannot
proceed to process the callback. Return a 'GARBAGE_ARGS' rpc-level error to
the caller instead.
If, however, the minor version field is incorrect, then we need to
propagate the resulting NFS4ERR_MINOR_VERS_MISMATCH error back as the
compound status field (setting the nops field to 0).

Finally, if encode_compound_hdr_res() returns an error, we need to return
an RPC_SYSTEM_ERR to the caller.
