[PATCH] nfsd41: nfsd4_decode_compound() does not recognize all ops

[Ricardo Labiaga]

The server incorrectly assumes that the operations in the
array start with value 0.  The first operation (OP_ACCESS)
has a value of 3, causing the check in nfsd4_decode_compound
to be off.

Instead of comparing that the operation number is less than
the number of elements in the array, the server should verify
that it is less than the maximum valid operation number
defined by LAST_NFS4_OP.

Thanks.  So the effect of this was to return an OP_ILLEGAL in some cases
where we should have been returning a NOTSUPP error?
