[ Upstream commit 36357fe74ef736524a29fbd3952948768510a8b9 ]
The scratch_buf array is 16 bytes, but I was passing 32 to the
xdr_set_scratch_buffer() function. Fix this by using sizeof(), which is
what I probably should have been doing this whole time.
Fixes: d3b00a802c84 ("NFS: Replace the READ_PLUS decoding code")
