RPCSEC_GSS: cleanup au_rslack calculation
Various xdr encode routines use au_rslack to guess where the reply argument
will end up, so we can set up the xdr_buf to recieve data into the right place
for zero copy.
Currently we calculate the au_rslack estimate when we check the verifier.
Normally this only depends on the verifier size. In the integrity case we add
a few bytes to allow for a length and sequence number.
It's a bit simpler to calculate only the verifier size when we check the
verifier, and delay the full calculation till we unwrap.
