NFSD: Copy FATTR4 bit number definitions from RFCs
I'd like to convert nfsd4_encode_fattr() to rotate through the attrmask using for_each_bit() instead of explicitly testing the bitmask for each bit value. This means I need the bit numbers, as defined in the specs, instead of our internal bitmask constants. As a clean up, use the new spec-derived values to define the WORD# bitmask constants.
